Tim Banning built 484 cuin. Moper block and heads. Original intake and exhaust manifolds. Very mild cam in the 500" range with full roller valve train. Edelbrock carbs .
I saw the build sheet on it a few years back and if I remember right, it makes just over 500hp and I think just under 600 ft lbs of torque.

In a 1970 Cuda, John Cope built 727, 3200 stall conv, 3.54 Dana. Running 295-50-15 tires. It will haze the tires at will at anything under about 50 mph without a whole lot of effort by your right foot.

Car is a blast to drive,,especially with the Vintage Air a/c system.
