4.3-> 5.7 quick question

[79k20350]

So Ive got a 1995 1500 with a 4.3 it thats got a knock from hell. Ive also got a 1991 5.7. Is the wiring pretty much the same? I know ill need to swap comps, but it would be nice if I didn't have to mess with the harness much.

Thanks fellas

Should be the same, some of the wires might be shorter, so might have to lengthen some...

Cool man. I figured they were close, I just didn't know if they had changed much through the years.

If not, the harness change is not too hard.
