Sorry..too many questions..but would appreciate the answers.

NASCAR motors are V-8 5.7ltr 350 cu.in. They do allow up to 358 cu.in. to account for overboring a motor. They've been limited to that size for quite a while. Output is a closely guarded secret but it's believed to be around 700-800hp depending on setup and around 500hp for a restrictor plate motor. Factories support privately owned teams. The reason for Carbs is that they are much easier to police than fuel injection.
