350 mopar ?

On a serious note............

Bastard engine swaps USED to be all about getting more power because that hardware is what you had to use, opposed to what "belonged."

There WERE no HP engines if you wanted to build a HP 40 Chev. You can only get so much out of a 235, so Olds, Poncho, Cad, "other" V8 is what you used

Same thing with off road/ Jeeps. There IS no HP engine for older Jeeps, so "most anything" gets swapped in.

But this---this is different. I see no reason NOT to sell the Chev and trade for a Mopar SB. Hell in "like for like" condition, you should be able to sell/ trade a 350 for a 360
