Re: Opinions on 327 build-up
I agree with Big Dave's suggestion. Why mess with the original engine? By the time you add aluminum heads, roller cam, machine work, balancing, etc, etc; the dollars will have added way up and your original engine will no longer be "original". You'll be better off with crate engine, especially since you say you're looking for cruiser, not custom race engine.
