thoughts of this set up

YS trim, and 347.

Its gonna make CRAZY power regardless if you stay standard bore 342 or go big bore 363.

personally i would go with cubes, those blocks are plenty strong enough even with the big bore.

oh, and theoretically, with the larger slugs, the motor would be more over-square. This would help it be able to spin faster, no?

I am looking into a dart 331 as well. Where is a good place to get one? I also was wondering if I will need to get better heads. I have Edelbrock aluminum performer rpms. Also, what would be a good intake? I currently have the crappy cobra intake. The goal is to slap a ysi or novi 2000 on it.

i'd go with the cubes, why not it's a dart block! you'll wish you did later if you don't imo...PB
