383 or 355?

[Soxxpuppet]

That question has been coming up in my mind aswell. I recently purchased a 4-bolt block out of a vette. After alot of thinking on the matter I decided to run a 383. Comparatively they would cost almost the same but the 383 would make tons more power and any rpm. As for the 24x, im sure you could get away without it for right now. But it would make life easier later on with tuning capabilities.
