c4 or c6?
 

Whats the difference? Weight I know but what so you suggest for a 450-500 HP motor. I have both so whatever you guys tell me would be really helpful. Thanks alot
You guys are great.

I personally would go for the c4 , the c-6 is a large tranny and a bit of work with a hammer is needed to get the tranny to fit secondly the c6 has alot more rotating mass than the c4, which adds to your drive trains total rotating mass which results in a loss of hp, if you were worried about strenght the c4 built with the right parts is good to around 1000 hp, the strenght of the c6 surpasses this but becuase of its bulky design isnt known as a great race tranny, the c4 on the other hand is light weight and relatively slim and holds up well to years of abuse!!! so
anywho its my 2 cents
