I beleive you would need a better fuel system.

I had 10# with heads and cam on my car and made 643rwhp with msd fuel pump booster.

How much boost were you actually getting with the better flowing heads?

That seems a little low. I have similar mods without the blower and I am making 532 rwhp/ 530rwtq. Should I only anticipate another 110 hp with a 10 psi blower? What numbers have other Roe recipients put down?

I think you need heads done to run 10#.

I would think you should be in the 700hp range with 10#s and the usual bolt-ons. (tubes, filters, cats, exhaust, 1.7)

A 10 lb pulley does not necessarily make 10 lbs , they are many variables: head work and so on. The way to find out for sure is, installing a boost gauge. The other advantage of the gauge is to see if you have belt slippage.

Or boost creep. Port match the intake to the heads.

with 10lb pulley I was actually making around 8lbs. Sean sent me a custom pulley to try but I sold roe setup and in the process of installing the Levin setup Chad Williams had for sale. I have pulley if anyone wants to try.

I'd be willing to try it. I'm going to upgrade my fuel system anyway.

What is boost creep?
