That’s about as far as you can push with pump gas and no additional air flow.
The same combo with either a well ported iron head or an out of the box alum would make 500+HP"
This is the cam they suggested: Butler/Comp SP Street Performance Billet Roller Cam (HR) 288/294, 236/242, .521/.540, 112 LS
I don't know if the experts here will agree with that or not. But, based on that with my planned setup (stock intake, no headers) maybe close to 450? That would probably be worth it.
