Re: 96 4.3 to 5.7 swap questions
Youve got a super easy swap on your hands. The 5.7 will swap in no problems. Fuel lines will hook right up. The v6 engine wire harness will work on the v8, but, you will need the v8 fuel injector plug. And weave/solder in the (4 total, 2+ 2-) extra wires for the fuel injectors. Youll need the wire diagrams to do this to setup the correct pins. It gets a little tricky with the 96 trucks because the abs is computer controled that year. So you can either try to use the v6 computer and have it reprogramed, ive never done this so couldnt give any insight on it. Or use an abs module from a 95 blazer, which is stand alone. You also have the option of removing the abs all together. All guages and functions of the truck will remain the same. Trany, driveshaft and rear will all work with the v8, no mods. I would recommend using a corvette radiator, late 80's model and in the foward position (inside the radiator support. And electric fan. Also, sell the v8 swap manual while you can, theres realy not a lot of info in there for 2nd gen trucks. If you have any doubts, think of the vortec v8 as a vortec v6, its pretty much the same thing.
