Is there a 4.3 Chevy engine swap problem?
Is there a 4.3 Chevy engine swap problem? 0 Members and 1 Guest are viewing this topic. Im look for some info on a 4.3 chevy engine swap. Ive read that the early engines have a balance problem at 1200 rpm but they fixed it in the later models. Is the 4.3L engine swap a good idea? The 4.3L tbi works great the wiring is not that bad. just add a seed sensor, frame mount fuel pump, 3 power wires and couple grounds. I'd suggest sticking with a throttle body or injected motor, it's going to run much more reliably...
