As for those other things, I would say IMO that they look like something to do with smog, pump maybe or vapor tank. Again, look for model numbers and identification numbers, everything has a number and it will help speed up the process. That one almost looks like a brake canister for a semi truck, lol.
Those parts are like a geological find that someone digging up historic objects would find 500 years from now. Probably say the same thing too, WTF is this?? :lmao:

I don't have a use for the carb LOL. Droppin a LSX in here, no more fuel leak controlled by vacuum LMAO

LS1 car intake. Needs to look like this vvv

Got the LS1 intake in today! She looks soo nice on the engine
Attachment 5813

Purdy!!

Looking good. Can't wait to see it start to come together

Where's the intake to your intake? juskidn...looks like a monster in the making.

My machine shop has a couple of LS engines that will be going onto the build room soon. I'll try to get inside pointers on what they do while there in there. Might be just some easy tricks to get you more HP. It all comes down to timing when I stop by. If I get then in the right place I can twist them for information.

Oh yea? Im keeping this engine stock, except for a cam and valve springs. Then im gonna put a big single turbo on it and run around 20psi on the stock bottom, and see how low in the 8s she will go LOL

Like your way of thinking! and by the way that pan (sump) is a lot shorter then on the chevy 4.3.

I'm curious, what are the measurements from the back of the block to the center of motor mounts?

Hmm...ill have to get back with you on that! But if it helps, this is a '07 4th gen engine

good progress on ur build.. how's it coming along?

Dead stop till I gather all the parts. Finding a transmission is the major part right now. And now that I have a full time job from 6pm to 6 am, I don't have time to do much at all lol

no commercial breaks, back to that build mista, lol

I use to like 12 hour shifts, though we got an extra weekend day on mon. or fri.
Use to deliver bulk Anhydrous for about a year , among other nasty chemicals to farmers.

The round-up weed killer was so concentrated you needed a permit to handle it and was dark brown instead of this clear crap stores sell.

Haha, nice. Im about to turn out storage room at our house BACK into a garage. That way I can build the trans in a clean environment and working on concrete beats the hell outa grass

Well the machine shop just got in 2 LS engines. So I'll try to see what they use and how they do things to make big power. These are your standard NASCAR engines. I know they put a carb and distributer on it. It's on the front cover.

Nice. It's hard to make ALOT of power on a naturally aspirated engine! I wont really have to do much at all to make BIG power on these LSX blocks. Valve springs, injectors and a cam is all you need for the engine. Then feed it some boost! But I'm going a few steps further. I'm adding a LS1-3 intake and some Holley fuel rails, and some LS9 head gaskets(used)! Then ill torque them down with an impact haha

Here are some of the main NASCAR engine characteristics that separate them from regular engines:
•The displacement is large -- 358 cubic inches (5.87 liters). Not many cars have engines this big, but the ones that do usually generate well over 300 horsepower.
•The NASCAR engines have extremely radical cam profiles, which open the intake valves much earlier and keep them open longer than street cars. This allows more air to be packed into the cylinders, especially at high speeds.
•The intake and exhaust are tuned and tested to provide a boost at certain engine speeds. They are also designed to have very low restriction, and there are no mufflers or catalytic converters to slow the exhaust down either.
•They have carburetors that can let in huge volumes of air and fuel -- no fuel injectors on these engines.
•They have high intensity programmable ignition systems so the spark timing can be customized to provide the most possible power.
•All of the subsystems like coolant pumps, oil pumps, steering pumps and alternators are designed to run at sustained high speeds and temperatures.

When these engines are assembled, they are built to very exacting tolerances (parts are machined more accurately), so that everything fits perfectly. Cylinders are bored to more exacting tolerances than street cars. The crankshafts and other rotating parts are balanced. Making sure that the parts are as close to their exact dimensions as possible helps the engine achieve its maximum potential power and also helps reduce wear. If parts are too big or small, power can be lost due to extra friction or pressure leakage through bigger than necessary gaps.

After the engine is assembled, it runs on the dynamometer (measures engine power output) for 30 minutes to break it in. The engine is then inspected. The filters are checked for excess metal shavings to make sure no abnormal wear is taking place.

If it passes this test, then it goes on the dynamometer for another two hours. During this test, the ignition timing is dialed in to maximize power and the engine is cycled through various speed and power ranges.

After this test, the engine is inspected thoroughly. The valve train is pulled and the camshaft and lifters are inspected. The insides of the cylinders are examined with borescopes (inspects the interior using mirrors). The cylinders are pressurized and the rate of leak down is measured to see how well the pistons and seals hold the pressure. All of the lines and hoses are checked.

Only after all of these tests and inspections are finished is the engine ready to go to the races. Insuring the reliability of the engine is critical -- almost any engine failure during a race eliminates any chances of winning

Well I havnt been on here in awile! Anyways, this is what ive been doing today! Picked up 3 TH400s!

lol, trany case at the bottom looks like a habit-trail for an ant farm. Glad to see your progressing again.

Yes it does haha. 2 of them were free and 1 was $50! I shit myself when I found them! Also when I was trying to unbolt the center support on the first trans(the one above) The bolt head stripped then I broke off an extractor bit in it...my luck

lol, You know it doesn't feel so bad when you can read about what other people are going thru with their trucks. Though, I do feel a little bit of pain for them because tomorrow it could happen to us just as fast. Time to start torching those old bolts or just soak the truck in anti-sieze overnight.;)

You didn't need to worry about that rust. It comes off the first time you stick it in gear, LOL

I know haha. The only transmission that I had hope in, isn't any unless I can get that center support out! Today I started the cleaning of the piston, rod and rings so that they will be nice and sludge free! PURPLE POWER FTMFW!

Hey guys whats up. Sorry I haven't updated my thread in awile. The truck is at a stand still uintil I can find a truck harness. If anybody knows where to find the ECU harness out of a chevy truck for the vortec engines (v8 only) let me know!
