My '75 Scamp 383 Build

I've run a budget engine that had bores that were slightly out of spec. It ran fine for my high school ride with a 318, though it's obviously not ideal. That big one may have some piston slap issues. I'm sure someone more knowledgeable than I will chime in. Just be prepared for the complete rebuild/overbore/new pistons comments. Everyone around here tends to like spending other folks' money.
