Re: Building A New TPI Motor
A.) Welcome aboard.
B.) Turn off caps locks, please. Typically associated with shouting.
C.) You're not getting that kind of power out of stock heads under a stock TPI. TPI intakes are not capable of flowing sufficient enough airflow to support that kind of horsepower. And in stock form, neither are any stock cylinder heads. Even with extensive port work, I don't think you are going to get 450-500. If those are really the numbers you want, you will have to go aftermarket.
