    well you can find a wrecked 87 up Ford Fox body and rip out everything and have an efi V8 but you'll need a hood scoop to clear the upper intake. If you find a wrecked 84-86 they came with a throttle body EFI in the auto's

    seems the only problem with my engine is the carb. a reman runs $400-$500,but i can drop a new weber on for $236.s0 $236=running 4banger or $300 = v8 with the headache of the swap.hmmm decisions,decisions....

    The 302/AOD swap in mine took about 3 weeks originally and drove the wheels off it for 5 years. As for EFI I'm going to be dropping on a MSD Atomic EFI system. Granted its $2400cdn but that about average for the aftermarket systems to replace the 4bbl carb.

    so what sensors and what nots are actually needed for efi conversion? is the computer and wire harness needed or can the sensors be hard wired to the ignition?

    i mean,say if i wanted to snatch up a manifold with the fuel injection from say a 1992 mighty max,would i need the whole wiring harness and computer,and i suppose high pressure electric fuel pump? never converted from carb to efi before so im open to any and all advice or input here.and Fordibishi,saw your pics and thats an awesome set up.

    Basically you need the whole harness, Computer and misc bits. High pressure external fuel pump, O2, and a few other things. You can set it up to be a stand alone system to just run the engine and fuel pump after you strip the harness down to basic's you are left with a 3 wire hook up for power.

    You would need the engine harness and ECU, both are pretty easy to pull. then you need intake with all sensors/injectors, MAF(air sensor) sensor, o2 sensor, anything else connected to the engine harness. Might be a thing or two more im forgetting

    DOn't the dodge motors fit better apparently since there is some type of relationship between Dodge trucks and dodge motors. I thought I read somewhere that the 318 is pretty close to a bolt in swap with minimal fab

    Nope Brad out of all the small blocks the Ford is the easiest with the front sump oil pan. The Dodge needs the most amount of fab work. the Chevy is in between.

    Nope you would need a wrecked thunder chicken and pull the engine,trans and wiring. the bonus about that is you can also run a wiring harness from a 2.3L Ranger (pre 88 single plug) or a 2.3L mustang.Then use the Turbo ECU and you have to move 3 wires in the ECU plug. I did the 2.3L turbo swap on an 87 Ranger 2.3L and it was simple, just ran the T-birds Rotary vain meter and added the wires to the harness. The other nice thing is the Rangers use and external fuel pump on the frame rail not an in tank one.

    Never seen a 4.0L swap but was thinking a 3.8 or a 4.2L would work too.

    They were are an emission thing. When they go bad they will cause backfiring. Bad vacuum problems. They have eliminator kits for about 30 bucks. It sounds like the timing is off by 180.

    yeah Camoit I also found out to I could just remove the adjusting screws and the valves are disabled and stay closed.also I removed my head and the valves,when I the valves,I MEAN ALL THE VALVES,were caked up with about an 1/8 inch of carbon build up,everything is cleaned up waiting on head gasket kit now.o yeah,alot of the vacuum lines were trashed,some just fell apart when I touched them others were just way to loose,making headway now
