383 block strength?

Agreed. Here is the thing that I never understood about a 383. Why run a big block that is the size of a small block, or smaller. It makes no sense to me. Now stroke one and you are getting there, but you still are short on cubic inches, and you are at the ceiling of the block.
431cid.

Bob Mazzoli swears by those 431 strokes.
Only way I'd run a 383 anymore. I have a 400 I'd build 1st. 361 cant even be bored to a 4.25 without over heating issues, seen that already. ..wouldn't think a 383 would fair well either.
