Will I be able to make 490- 500rwhp with what I have?

You will still be making the 9psi power....porting and more airflow are wierd like that....long story too hard to explain.

I think that if the porting is done right you may see 490. 500 is prolly asking a little much. But I am sure someone here will say you will see 500.

I only picked up about 25 hp when I fully ported my old TW's on a car I used to have. But when you factor in a blower, you should see 30-35
