I currently have 9.1 to 1, what would I need for a cam and compression ratio to hit over 1K hp?
If you can make peak HP above 7500 RPM, approaching 8000 RPM .. > 1000 HP *should* be possible with 11 to 1 compression.

Ideally I'd want around .950 lift at the valve. If your heads have the CSA and run around 450 CFM or better on a flowbench? and intake/carb to match requirements.

Unfortunately they don’t flow anywhere near 450cfm, the intake at .950 lift peaks at 388cfm.
