What heads?
what pistons?
what crank?
what rods?
what is duration @ .050?
What carb?
Loose the Performer and go with Performer RPM or Stealth!
with my guess of 9.5cr and stock length rods/stroke, and a decent guessat that cam lift/duration, you should be maybe 300hp at the flywheel, meaning 240 to the wheels(estimating 20% loss), and theoretically you would do a 13.7 max with that much power, if you dead hooked and all.

Thanks for the reply!!! The heads/piston/crank/rods I don’t know what kind they are. Duration is .050 carb is the stock Rochester q-jet I had it rebuilt a year ago intake is an Edelbrock RPM I said Performer I was wrong I thought it was the same thing for some reason.
