4.3 to 4.3 vortec engine swap

Asked by Jan 19, 2017 at 12:06 AM about the 1992 Chevrolet C/K 1500 Silverado LB 4WD

Question type: General

Is it possible to replace my 4.3 liter V6 motor with
a 4.3 liter Vortec V6 motor and if so what would it

3 Answers


the computer of the engine going into the vehicle being upgraded. all wire harnesses too. be sure to make the fuel pipes fit. those are just some of the things to watch for. research online too on youtube.


Engine, harness, pcm, fuel pump, the ability to custom wire the vortec harness to your truck for gauges and the ability to start and what not. It's more cost effective to sell your truck and buy a 96+ with the v6 already there

can I put a 2001 s10 4.3 vortec extended cab 2x4 engine into a 1996 regular cab 2x4 s10 truck? And how much trouble would it be?
