I got 200cc's for my 415 stroker. I wanted 215cc's, cuz i had read tons of build ups and the common choice for a 400+ cid motor was usually 215-225cc's. But theres always a problem. If i bought 215cc's I would have to had bought another set of valve springs cuz you couldn't get ones that would match my cam. So I settled for the 200cc instead. My truck isn't on the road yet, but so far I'm overly please with my motor. It has a deep throaty sound and everyone that listens to it run acknowledges how quick the motor rev's up. Once I get it on the road it may not even have enough power to pull itself, but all indications right now is has no problems breathing at all!
