Horsepower limit for out of the box Edelbrock RPM heads

I'm more interested in engine responsiveness. When you are driving a road course or cone event, the engine spends a lot more time back and forth in the mid-RPM band than it does in the top 1500 rpm. The the throttle isn't wide open all the time. An engine that is dead below 4000 rpm might work for a drag car with a 5k converter, but isn't going to pull the car out of a slow speed corner very well. Obviously the "package" has a large effect on the performance, but it is difficult to pick a gear that is going to be perfect but I think a 3.55-3.91 is the likely choice until/unless an OD manual can be funded. There is a limit on how much gear you can run and still drive it to and from the events.

Interesting post, when I called Jim at Racer Brown for a custom grind and told him I intended to ultimately road race the car he basically explained what you just said. Peak power won't be as important as having instant throttle response and a wide power band to shoot the car out of the corners. "You're gonna be mashing that thing all the time at different RPMs and you want it to pull hard every time," or something along those lines is what he said.
