Answer to your problems and yes they dont hook up for crap 662hp/600rwhp on a 9.5 inch rim wont hook up i dont care who is driving it . I dont think it's unfare to comapre these to cars thats what racing is about anyways ,ones heavier ,ones lighter .427 vs 351 S . Keep in mind the heavier one is forced induction while the lighter one is NA Big cube .Sounds fare to me .I never had any issues racing Z06 and i havent lost yet ,if anybody in the San Antonio area wants to try to change that let me know ,as long as it doesnt have a parachute on the back i wont bitch lol .
oh snap bet the big bad gt500 killer wont step up
