I do all my own wrenching and have a general idea what needs to be done to make this swap. Are there any tips or secrets I don't know about when swapping from mpi motor to carb motor? Thanks guys.

Look up Noise Pollution on here. He went from a fuel injected 502 and built a 540ci. carburated.

nope, just did it...EFI harness unplugs, just have to ck distributor and change fuel pump...no big deal...

Awesome. I guess my biggest concern was the mercruiser big plug. It should plug right in to the new motor. It's coming out of a 98 Baja. I'm just pulling my motor out and dropping a different one in. So hopefully all my gauges will work.

yes all wiring the same as far as I know...they just add EFI harness on top of the std carb style...
