Engine swap - 99 5.7 into 95 C1500
I have a 1995 C1500 with a worn out 4.3 V6. I got a great deal on a 1999 5.7 complete with the entire under hood wiring harness, computer, and all of the sensors including the mass air sensor. What do I need to make this work?

first question is did you get the trans with it, the V-6 unit wont last past your first attempt to smoke the tires, notice I said "attempt". then you will need to mary the wiring harnesses, you will need the 1995, and the 1999 wiring diagrams. go to your local library, they should have the GM service manuals, and you could copy the under-hood sections. then get to work. also will need a v8 radiator and shroud, also exaust manifolds. should be real simple. motor mounts do not move between the two I do believe. you will have to mod your fuel lines to join up, I used compression farrel brass fittings and hi pressure rubber hose. YOU will need the fuel pump out of the '99 cpfi 60psi unit verses 45psi in the 95 TBI system(both are return line vacuume referenced systems or get an inline hi pressure pump and feed it with your 45 psi stock unit.
