I'm hoping for about 425 - 450hp by the time I add Edelbrock heads and more cam. I want the torque not the high winding rpm so planning not to exceed 6k.

The motor I have was built for another Cobra and had a Offy 360 single/dual manifold (looks like a single plane but has a divider.....strange). It was running very rich and ran out of gas at 5500. I live at 7000ft so that's probably most of it as well as poor carb jetting. The PI manifold should improve things as well as the Edelbrock heads. I'm probably going to have to go with a 600cfm carb but we'll see. The other car this motor came out of also had a 3.07 rear end and that was the major problem. My 3.54 should help that too.

Thanks for your information. I'm going to keep the PI on the car based on what you said.
