The motor that you are building is the twin of the first bracket 440 I built more than 30 years ago. It was a .030 over motor with the L2355F forged pistons, heavy rods, stock stroke steel crank, factory balance, iron "906" heads with stock size valves and factory porting. I last ran a DC solid cam 296 degree .557 lift and had no clearance issues. The car weighed 3,700# with driver and ran about 110 mph in the quarter. There are math formulas to determine horsepower based on weight and quarter mile speed. Your engine will have better heads and a pro assembly job, so if it does not run better than my old motor something is wrong with it. It should be fun to play with. Good luck.
