yea that was my first plan like 3 months ago, but i was told id have to rebalane the whole engine because the cam was and the rest of the parts were balanced togther and if i threw a different cam in id have to rebalace the parts and make sure the heads and and engine would be able to support the cam, figuring you biuld the engine around the cam. but i figure id have to do all that anyway if i put performance parts in. and also i heard if i up grade the engine, or put different parts in, the warranty is void. but yeah it is real hard to beat.
