I was asked to post a page on my build. I will do my best, but I'm better at wrenching in the garage than I am at taking pictures, posting and giving descriptions. Actually I have never really ever posted in any forum, so please bear with me.

My dad bought this truck brand new in '86 and it's was I learned to drive when I turned 16 in 1991. I have kept the truck all this time although it has been in storage for the past two and a half decades.

21299

This is the garge where the swap is taking place, it's small and generally a mess as you can see, but it's heated and fits everything I need.

21300

The first test fit I set the engine by aligning the 904 with the stock automatic transmission mount as I've seen most other people have.

21301

Although this approach would make things easier as far as shift linkage, drive shaft and etc.... I felt better getting the engine to sit back as far as possible without serious firewall modifications. What I found was if I used the original D-50's automatic transmission mount (the soild block that bolts to the trans) 180° it moved the engine back two inches. Sorry no good pictures of this, but if someone is doing this you might get what I'm talking about.
21302

I had to use button head bolts for this to work. They we're a bit difficult to find, but I did get them from http://mmsacc-stainless.com/.
21303

Since these bolts are no longer accessable I drilled holes in the cross member to access the two regular bolts that go in from the bottom.

Next was on to the motor mounts. I wanted to incorporate the stock mounts, as I want to go with a oem look, but could figure out a way to do it and keep it structurally sound. This is what I came up with. I'm not positive if this will be the final set, but I do like how it spreads out the the support of the engine to multiple points and hopefully aid in twisting the frame if the truck desides to hook up.
21306
2130721305

After the engine and transmission we're mocked up in place it was time to get a drive shaft built. I wanted something beefier than the stock shaft, but also wanted to keep it a two peice shaft. The truck will be kept lowered and if I end up getting serious about taking it to the strip, I have concerns about a one piece drive shaft would hit the fuel take cross member mount if the rear would squat. I know there will be weak links in my setup, but I'm not for sure if I'm just going to be crusing the streets or possibly more. You're welcome to point them out but I'm aware. For one I will be running the stock rear end for now. I did get a LSD off of Amazon (Precision Gear LOM83 Power Brute Limited Slip Differential) which fit perfectly. I believe it's a bit cheaper on eBay, but I wanted to make sure I would not have any issues if I had to return it.

The stock transmission cross member was notched to support dual exhaust. I notched it out and filled it in with a 4" pipe one half in the cut out and the other half above to keep it structurally sound. This may interfere with the stock shift linkage, but I will tackle that when it comes up. It will need to be modified anyway since the trans sits back 2" for the stock location.

The starter is a bit of concern, this is the biggest issue I've had with sliding the motor/trans back torwads the firewall. The stock magnum 5.9 starter hit the steering box. I picked up Powemaster XS that is clockable and it does clear the box and idler. It's close and I believe I won't have any issues when the engine torques. Worst case scenario I do have wiggle room to move the engine to to right of center.

I did massage the firewall a bit where the transmission/engine bolts go. Everything cleaned just fine but I wanted some extra room to get fingers and and a wrench in there. I will smooth it out when body work starts.

I did purchase a LA timing cover and water pump, but the snout of the pump was to long for my liking. I lost the ability to run a mechanical fuel pump by going with the Magnum set up, but it gave me another inch or so clearance for the radiator. The radiator I found would fit behind the support.(Griffin Universal Fit Radiators 1-55201-TS) I do want to cruise the truck and have a fairly decent built engine, cooling is going to be important. I went ahead and cut the front support out to the size of the radiator and will shroud it with two 10" fans pulling air. From what I understand pulling air if more efficient than pushing it, hencs putting the radiator in front of the fans. I will also be running a fan on a oil cooler I plan on running under the bed of the truck. Like I said I don't want any issues with cooling. Trying to keep away from the hacked up look I drilled out all the spot welds and cut the least amount of sheet metal as I couldn't. Once the radiator has found it's permit home I will take the remove metal and patch in back in, trying to keep that OEM look. This I'd the current project so, more pics will be coming.

A little about the engine, It's a 5.9 magnum out of a '98 truck. It has a balanced bottom end, flat top standard bore pistons. Fairly large street/strip cam from Hughes, aluminum heads running 10.7 to 1 compression. On paper it should produce 450hp/450torque. If anyone wants more specs I can provide more details.
21316
21317
21318

Trans is built 904 with 3500 stall.

As I mentioned before, I decided to keep the Magnum components on the front of the engine, mainly because of the shorter water pump. Originally I wanted to do a LA conversion, but this set up gives me that extra room and saved a few dollars as I bought a complete engine.

I did modified the serpintine belt configuration as I deleted the A/C and power steering from the donor. I couldn't find any delete kits online so here is what I came up with.
21319

First thing I did and for those who know the magnums was to cut the huge accessory bracket in half and get rid of the a/c mount. I used a sawzall and leveled it off with some heavy grit sandpaper. After running down to finer grits the final polishing of the aluminum was done with a headlight restoration kit.
21320

I had to add an additional idler pulley to get sufficient surface area on the water pump pulley. The mount comes from 03 to 07 Ford f-350, but needs to be machined down 10mm. I picked mine up off eBay (Continental Elite 500008).
21321

I also had to down size the stock idler and used an ACDelco 38006 to make room for the belt circling back. By mistake I ordered 6 rib idler pullies and just went ahead and used them. The OEM belt is 7 rib. The belt that worked for me was a Bando 6PK1765

This was a spacer I had laying around to mount the return line to the water pump.

Radiator is in place.
21388

Had to trim out the lower support to get it to fit. Radiator is from Griffin and measured 24" wide 16" tall and 3" deep.
21389

The center support is still be needed to support the hood latch and the spoiler, fabricated a new lower mount.
21390

The radiator cap will be unaccessible, so I will run a higher PSI cap on the radiator and add a inline filler to the top hose with the appropriate cap. I'm going to place a rubber strip ( old mud flap or something similar) under the radiator for a lower support. There are two upper supports that bolt into the upper support. I will line these with some adhesive back rubber for further cushioning.
2139121392

There is a aluminum shroud holding two 10" fans pulling air through the radiator. Power is coming in from a relay/fuse box I placed in the engine compartment. It also supplies power for the fuel pump, oil cooler fan and wire ran into the cabin for future use.
2139321394

It's a tight, but it all fits. I really wanted to run a fan shroud and keep the stock hood latch. Luckily I was able to accomplish that.

Here are a couple more pictures of the engine bay. Almost there, still need to build the exhaust, hook up the fuel lines and make up a throttle cable and set up the kick down. The plan as of now, if all goes well with breaking in the engine, I will be taking down to speedway. After that the truck will be disassembled all the way down to the frame and body work will start.

Not much to update on the build. I pulled the engine to finish up welding the motor mounts and radiator support. I then decided to start rebuilding the front suspension so when I drop the engine back in I can get a feel for ride height. Im just about ready to reassemble the left side. Something I was taught back when I sixteen on doing drum brakes always do one side at a time so you can use the other for reference. This is how I've taken the approach here. I have the service manual and my 84 mighty max also, but it's much simpler to just glance at the other side of the truck if I'm questioning fitment.

All bushing, joints and tie rods are being replaced with Moog components, always had good luck with them. I wanted to stay with rubber bushings up front to keep decent ride quality, the rear will be energy suspension in hopes of controlling wheel hop amongst other things.

I am replacing the stock coil springs with Moog's heavy duty 2278s they have one more additional coil and the coil diameter is around 1/16 larger. Spring height and diameter look to be the exact same. My stock coils have had a 1/2 coil removed but, here's a picture for comparison, they arrived black and I added some blue paint.
21560

I will be changing thing up down the road with drop spindles and gen 2 brakes. Does anyone know if the upper control arms from gen 1 and 2 are interchangeable? I like the idea of having rubber bushing in the upper control arm. So, as things are now this is what it looks like.

21561

21562

geezer101
01-21-2019, 12:07 PM
AFAIK the geometry of the Gen 2 control arms are identical to Gen 1's as you can swap steering hubs and brake assemblies without screwing anything up. The UCA pivot shafts may be different in design but that's about it (there are different part numbers and some members have run into a situation where they've bought them and they didn't fit)

travhous
01-21-2019, 02:53 PM

For some reason I was thinking the 2nd gen pivot shafts road inside rubber bushings. I just looked up the schematics and they appear to be the same as the first gen. Don't know why I thought that. Hmmm

01-24-2019, 06:44 PM
as Geezer said there are 2 types of ucas - 1 with metal bushings and one with rubber. Never figured out which ones had which arms. To save you the hassle of repeatedly replacing lca bushings, use urethane - rubber will egg shape in 5 - 10K miles, and the ride is not different with the urethane bushings

And the front end/steering will feel like it has a more positive feedback. The rubber squishes around and the older the bushes are, the more it'll feel like a boat. Replacing as many of the suspension bushes with urethane is the way to go ;)

travhous
01-26-2019, 02:17 PM
I totally understand the benefits that come with urethane bushings, but my preference is the rubber as these trucks tide rough enough for me already. I've gotten 50,000 out of Moog rubber LCA bushings on 1st gens, the stock ones are another story. LCA bushings aren't bad to change is you have access to a interal spring compressor. Just drop the shock out compress the coil spring unbolt the LCA from the cross member and slide everything out the back hole. A little bit of silicone to install the new ones.

One side pretty much done.

Slowly but surely, the little ram is coming along. Front suspension is fully rebuilt and done. The new heavy duty Moog springs seem to be supporting the extra weight of the 360. I just set the fully dressed engine and transmission with torque converter this morning so have to wait and see how the springs settle, but it looks to be at stock height.

Anyone know what the original 2.0 or 2.6 weighed? I weighed the full dressed 360 with 5.5 quarts of oil and it was 488 lbs. Pictured below.
21856

Engine bay is all cleaned up waiting for the final insulation of it brand new 360.
21857

And finally and hopefully the final install.
21858

I brought this up earlier and thought I would talk about it again being it was one of my biggest struggles. Most of the V8 swaps I've seen they install a 904 transmission in the stock location and start building from there as I did also to start off with. It just bugged me look at the space behind the engine to the firewall and figured adding a few hundred pounds to the front I wanted that weight to be as far back as I could get it. Getting the starter to clear the steering box was the biggest obstacle. After moving the transmission back 2" from the stock location I ended up offsetting the engine and transmission towards the passengers side a half inch from center. I figured this should help balance the truck as the fuel tank and battery are on the driver's side. Heres a picture of the clearance I have in the final install.
21859


If all goes well next post could be a start up video.

Oh man that is a tight fit. Left hand drive vehicles have all kinds of different obstacles when doing a project build. I could easily bang a turbo'd 4G63 in my truck and not have to worry about an intake manifold hitting a brake booster or going V8 and not even think about the steering fouling something, but there's a bit of an art to planning around steering boxes and brakes etc working on a left hook. Top marks to you :clap:

travhous
02-27-2019, 09:55 AM
Got everything bolted back on and the suspension is still holding the extra weight which is great. Will be installing 2" drop spindles and 2nd gen brakes, blocks in the rear for now. At some point I will be getting a custom built rear axle and building custom suspension.

Trying my best not to chop up the truck and retain as much of the OEM look as possible.

I found an instrument panel out of a 4x4 with the tachometer and was able to swap it in. Had to swap a couple of wires around in the harness but was really pretty simple. I removed the check egr light for an oil pressure light. I used a tachometer signal convertor from Dakota Digit to make the V8 play nice with the 4 cylinder tach.

I also have the factory oil pressure gauge and ampmeter that go below the center vents but, haven't decided if I'm going to use them. I have kind of taking a liking to having the 1 1/2" gauges in the stock radio location.

It's been a while since I have posted and figure I would give some updates.
23765
Swapped out the master and booster from a Stealth/3000gt. The original master cylinder had a 7/8" bore compared to the 3000gt's 1" bore. I was a bit concerned that the brake pedal would become to stiff with the larger bore, but it acually feels really good and not nearly as spongy as the original. The power booster from the 3000gt has more capacity and surely helps with the larger cylinder bore of the master. I have a large cam and very little vacuum at idle so, I also added a vacuum pump from a late model Chrysler hybrid mini van. Also, swapped spindles, rotors and calipers from a 2nd gen.

23766
Found that the air dam from the early S10 is almost a perfect fit under our gen 1 air dam, just had to trim down the ends a couple of inches. My hope was the extra air dam would create more negative pressure under the truck and help pull more air through the radiator. What I found is the truck feels much better at highway speeds and above. And I just think it looks cool.

23767
Added line lock for the brakes.

23768
23769
I couldn't find wheels in the width and offset I needed, so I decided to build my own from the original d50 steel wheels. The original center section is spot weld the outer hoop. If I remember correctly I used a 1" hole saw anf drilled out the 8 spot welds then was able to press them apart. Original wheels were 14"x5", the fronts are now 14"x7" wrapped in 205/70s. The rears are now 15"x8" wrapped in 275/50s. Not really any reason why I used 14s in front and 15s in the rear other than that's what I had on hand. I just wanted to see how it would work out and what they would look like. They have been growing on me and they might just stay. Center caps came from a GM truck.

23770
23771
Fabricated some traction bars based off Caltracs.

23772
23773
23774
23775
Relocated the battery behind the right rear tire. After moving the battery and putting the rear bumper back on I took the truck back to the scale and I now have 56% front and 44% rear weight distribution, I'm very pleased with that.

23776
23777
23778
Installed the MSD ignition box on the right kick panel, below that is the radiator fan controller.
Had a gen 2 fuse box I mounted under the glove box for all the electrical stuff.
Trying to clean up the engine compartment, I was able to reroute the wiring for the right side lights, horn, windshield wiper fluid pump down the left side and up and under the radiator support without cutting any wires. Really gives it a cleaner look.

23779
I believe I mentioned earlier I swapped in a instrument cluster from a 4wd so I could have a factory tach. Im now using the check egr light for oil pressure warning and the green 4wd indicator is now lit when I activate the line lock.

Will do my best to keep updating the progress, just been busy building and taking the old d50 for some really fun cruising.

Next up is reinforcing the stock rear axle hosing with a truss. I had a spare rear end I disassembled and was impressed with the 1 1/4" axles and beefy bearings, looks like the housing may be the weak link. I'm hopeful it'll hold together for a while.

You've done such a great job of tying it all together. You're using the same type of relay and fuse block I bought for my truck too - it's almost in the identical location as well. The battery in RHD trucks is in that corner of the engine bay but I'm really considering moving it for both esthetic and weight reasons.

I bought the battery box from Summit, I'm thinking for around $15, well worth money over fabricating on. The silver rods running up are the battery tie downs. It does pivot by removing the angle from the base of the box up to the frame. Set up works really well.

Trans dipstick is pretty much the same as Lokar, I believe I got it from Classic Industries.

Thanks for the nice words.

All bushing, joints and tie rods are being replaced with Moog components, always had good luck with them. I wanted to stay with rubber bushings up front to keep decent ride quality, the rear will be energy suspension in hopes of controlling wheel hop amongst other things.

I am replacing the stock coil springs with Moog's heavy duty 2278s they have one more additional coil and the coil diameter is around 1/16 larger. Spring height and diameter look to be the exact same. My stock coils have had a 1/2 coil removed but, here's a picture for comparison, they arrived black and I added some blue paint.

Update:
After running the Moog springs for six months they compressed down way more than I liked. I was doing the 2nd gen brake swap and decided to put stock springs back in it, so far they seam to be much better than the Moog.

I was getting some weird front tire wear, so at the same time I did swap out LCA and strut rod bushings with polyurethane. Very happy with the results.

Original brake lines, only thing I added was one short section of steel line to the line lock and everything is uncut and oem.

To mount the Stealth's brake booster I had to drill two holes in the firewall for the lower studs. Used the Stealth's aluminum spacer between the booster and firewall and the brake pedal line up perfectly.

I did a similar thing to install the BMC out of a Gen 3 (think it was a Gen 3...) Pajero. The 2 top brake booster studs lined up with the steering column/brake booster brace holes. I cheated a little by using the Gen 3 brake booster spacer and used the bottom through holes as a drill guide and went through the firewall with a new 8mm HSS drill bit (I dummied the spacer in place with 2 x 8mm bolts and flange nuts so the spacer was held exactly where I needed it) Had to do some sketchy free hand bending of the existing solid brake lines, but it appears to have worked fine.

Building custom headers and have one side pretty much finished up. Went with a tri-y design just to simplify things and there just isn't much room to work with. I purchased cheap stainless headers off eBay and cut them up to build these. Much cheaper than buying all the tubing, got a few sets for around $45 a piece.

...and they'll probably be better finished compared to how you got them. Nice work! I have a similar idea to use headers from an NA Talon if I ever get the chance to go twin cam. I can get them relatively cheap but the freight will burn me.

Question regarding your gauges. Are you able to use the factory speedometer? If so what did you need to do to keep it?

My truck was originally equipped with the baby 904 automatic transmission which is nearly the same as the v8 904. Original speedometer cable hooks right up, just had to swap the speedo gear in the transmission.

Truss for the rear axle housing. I'm curious how far I can push the the stock differential and just trying to save a couple dollars.

New exhaust tips and put the rear bumper back on for more rear weight. Took the bumper off over 25 years ago and I actually like the look of it back on the truck.

Headers wrapped and installed, ended up taking few days to build both sides. First time building headers and they are a tight fit.

if that were my truck i would have chrome bumper under it, but thats just an opinion. i really like it. i love these little trucks and i want to do so much with mine but i cant, so right now i am looking at a 1992 D50 2wd reg cab short bed to convert into a SRT4. i want to do a cummins swap on a power ram. might do it with the 82 and a clapped out cummins just for shits and giggles

Keeps more heat inside the tubes, hotter gases flow faster. Also lowers under hood temperatures.

Awesome stuff travhous :thumbup: Good to see someone going all in and making sure it's done right. The header wrap is a good idea, especially with how tight you've got the headers up against the engine. Would've been challenging to get it all together.

I had to replace the transmission and decided to do some improvements on my tranny mount. I thought I would share what I think is a easy solution for the 1st Gen crossmember if you're doing this sort of swap. Find a 2nd Gen crossmember and things should be much simpler. The second generation has a pad welded to the rear of the crossmember compared to the first generation where the trans mounts right in the center. If running a 904 tranny the stock automatic mount should bolt right up. I tried to run the first gen mount and it was not nearly strong enough for the v8 swap. I'm going to stick with the crossmember I have been using because I would have to many things to change like exhaust and etc... But if I had to do it again I would use the gen 2 crossmember and hope this might help someone doing the same kind of build.24626

i gotta measure up that 2nd gen trans cross member and see if it will work with mine
