405 rwhp seems a little weak with heads and a cam, what exhaust are you running? If the 241s made the same power the Patriots did, no one would spend the money on em.

With that cam, I could see you making 405rwph with the 241's, but you should have been close to 430rwhp with the Patriot heads. So to answer your question, yes, there is a significant difference.

ok well i dynod it at one place when i first got the car and it did yes make 430hp, but the car burned oil sooooo bad, is it possible that the rings going out or something could have been seriously hurting the hp over time if the heads were getting bad?
