I'd like to see you build it. I think you would need a cam in the 255 @ .050 range, a cylinder head over 300cfm and at least 11.1 compression.
I think you'd have to spin it 7400+
that enginemasters 318 I spoke of earlier I shifted at 6200.
with the enginemasters cam(247@50) it peaked at 6500.
the heads were PLENTY to support 10’s. They went low/ mid 270’s at 600 lift.
no need to buzz it more than 66-6800 to have run 10’s.
I thought about keeping the motor to prove 10’s.. but I am not a fan at all of magnum stuff. Don’t like the Chevy style top end.
sold the motor with the car
