Fixing vs. Buying a New Engine / 273

the tricky thing about going to a bigger engine is what rear end does it have?

if it has a 7 1/4 then that restricts you to a 318 or smaller ....a 360 and possibly a 340 would snap a 7 1/4 like a twig.

also what are you doing with the car?

if you are just cruising and don't mind stock specs ...then fixing that 273 should cost much I rebuilt a 318 to stock specs for around $550. and that was a lot of new parts but all to stock specs.
