Ideal Drag Race Bore and Stroke

I look at my last build, and chose a 4.315 stroke ccw crank i had over a 4.560 stroke crank i had because i felt the ccw may provide better ring seal in an aluminum BMP block, so i got 549 cubes. It made 900 hp at 6400 and 980 at 7600.
The bigger crank would be 580 cubes, and would drop max power rpm down maybe a couple hundred rpm, but add needed torque at 6400 where my stall is now with the 549. If i was wrong on the ring seal idea, and it was the same, i would gain an extra bunch of hp in the first half of each gear, making the bigger motor faster, and at a bit less rpm. Since i have stainless intake valves and best performance was shifting at a recorded 8,000 rpm, it would be a huge benefit to my valvetrain life. So that is how stroke affects my motor building; for me and my needs the more you can use easily the better. My big mistake was not having that ccw crank made (Crower) in 2003 with a bigger 4.625 stroke, which i believe would have been as big as easily fit in the megablock i had, making 588 cubes. Being able to keep rpm down around 7500 would fit my valve strain combo
