My 426 hemi has a crane mechanical roller with almost the same spec's as your's. It has untouched mopar aluminum heads and a stage V 2-4 manifold. I run a mechanical carter street strip fuel pump. This engine will pull easily to 8,000 rpm. 3800# cuda with 3;54 dana 4 speed. Sorry no time slip as the car doesn't have a cage. Have ran up to 135 mph and had plenty left.
