As much as it dulls the appeal for me swapping to chevy power, I can't think of a single LOGICAL reason not to do it. Parts O plenty, less cost, and often more power. Hell, if you buy used chevy stuff it's usually 8 cents on the dollar too. Good luck finding something good used in a mope.

Need a chevy block, you have 10 or more choices new, on shelf, same day, and countless used ones.

Hey I need a Mopar block,,,and a time machine.
