How much would you spray at this set up?
455 pontiac block .30 over 463ci. Cast steel crank 4.210 stroke, forged pistons and rods 10.5:1 compression. Ported edelbrock performer heads flowing above 300cfm. 825 mighty demon carb. All through a th400 3700 stall on the trans brake. Have a plate set up but curious as to what my limit should be.

On my 69 I had butler performance ported Iron heads (6x) on my 462 with the trw forged pistons and reworked rods, on a stock crank. was running a comp solid roller cam in it with the performer RPM intake and a holley 850. I had mine jetted for a 250 shot and made a ton of passes on the motor and never had any problems, just be sure to pull enough timing out of the car, your compression is a little higher than mine it was 9.75-1 but your running the aluminum heads, and can get away with it they dissapate the heat alot better.
