Re: engin swap on my 93, 1500, V6, what should i put i
I have done a V8 swap into my V6 1988 GMC. It is not a hard swap if you plan to keep the throttle body injection. I did a swap to a carbureted engine, but I did alot of research on it and found out a lot. The wiring harness should work. The accessory bracket and pulleys will work, but you will need at least the V8 shroud (any maybe fan?), but it's a good idea to get the V8 radiator too. The motor mount adapters will need to be unbolted from the frame (front coils will need to be removed to do this on 2wd) and you will have to switch to the clamshell mounts that the V8 uses. As far as the computer. I'm not sure if the V6 will work with a V8 chip, but I do know that the harnesses for the V6 and the V8 should be the same. I Also believe that all of the sensors are interchangeable. The benefit of going to a 350 throttle body injection is that you wont have to modify the emissions or fuel system to fit the V8. The fuel system uses the same connections. Also, you will not have to fool with aftermarket guages as I did. I am still without a speedo due to RF interference from the aftermarket ignition. I think in 93 they had the 700R4 in there and you might want to check model numbers. I know with the TH-400 they sometimes put a smaller set of clutches in. I dont know if the 700R4 was like that. I lucked out and mine was the same as the V8 TH-400. Also, I dont think you will need to change out springs for the weight difference, my truck sits the same as far as I can tell and my engine is entirely cast iron, no aluminum heads or anything. The fuel pump is the same model as well I believe. If you have anymore questions, ask me. If I dont know the answer, I'm great at researching stuff.
P.S. - I swapped for a 383 stroker and am in the process of setting up my truck for drag. [img]images/graemlins/burnout.gif[/img]
