I have a 1998 s10 with a 4.3 do I need to switch frame mounts to put a v8 in it thanks
The Vortec swap is supposed to be a nice one. Pretty much uses your existing wiring harness and all accessories with only minor mods to the wiring harness. As Eric said, the radiator is best put into the "forward" position by modification of the existing radiator support or you can buy aluminum ones that that fit "forward" without modification. This is required to clear the extra two cylinders you are putting in the front of the engine bay.OK I found motor mounts and frame mounts I'm going to use s10 2.8 mounts that are aftermarket ones that has no rubber in them. I been doing a lot of reading how to get my 5.7 vortec wired up don't look to be to hard to do. Sound like I have to get my ecm re flashed or get it re programed.
Manual trans complicates things immensely for exhaust. Why few people do it. Better to go with automatic, if vehicle had one originally. If S10 was original 5-speed I would make sure you want to do this swap before you get started. You won't get A/C and a radiator in stock location to work with a V8. They don't go back that far. In a S10 the engine goes where the engine fits, and where everything attached to it clears!Thanks for the info I'm going to run a vortec 5.7 and a 5 spd transmission I would like to put the motor as far as back as I can I want to run ac
My S10 is a 2WD. My Blazer is a 4WD. I've been talking about the S10.Thanks mine is only a 2 wheel drive I know exhaust would be hard to do with the fuel tank in the way that is why I thought of going with side pipes most of the headers they say they don't fit manual transmission I will have to call to make sure
