My next ? is
I have a 416 in my car with these heads on and it dynoed at just under 600hp and 550 torque. Hp at 6100 and tq at 4600.
Will I see much more by going to the 450 or am I at the top. I am running 10.6 cr and would like to stay using 92 octane pump gas.
may not see much more HP, but you should see about 8-9% more torque. I'd guess on the same dyno it'll be ~620hp max and about 600 tq, with peaks about 3-400 RPM lower than you saw on the smaller motor.
