  • 258 to 304 or 360 swap

    was wondering if I could swap the 258 with a 304 or 360 without changing alot. would i still be able to use bell housing and be able to bolt back to existing 5 speed?

    go talk to these guys I put a 401 in my yj and the helped me alot all i can tell u is i dont think so but i might be rong amc made a few bellhousings and i think u have the rong one plus your 5 speed is to light of a transmission for the 304 or 360 u need a tcase 4 speed like a np435 or a t18 if u have question about trannys go to and read up.

        258's are awsome but that's just my opinion
