Stop in for a cup of coffee

If you swap a 318 in there, you should upgrade the axle as well... I blew up three 7 1/4" axles with a mild 318 with a 4 bbl and dual exhaust... I then went to an 8 3/4" axle and never blew one of those on the same 318 for over 200 k miles...

My understanding is that if I went that large on an Early-A I would have to shorten the axle?
