You need to look at high end builds but it's not necessarily in what parts they use but they do with them, here one build that fits the bill an engine master competition motor not the show but an actual competition, it's a 360 bored to 371 making 515 hp @ 6000 rpm's and 495 lbs-ft @ 4800 rpm and over 400 lbs-ft 2500-6500 rpm, that's the torque of larger like a 408, and hp at reasonable rpms. Pretty sure this is one of the builders on here.

371ci Mopar Small Block - Popular Hot Rodding Magazine

The judging for the EMC for that year was based on three consecutive pulls from 2500-6500RPM.
With a cubic inch factor added in to take into consideration the variations in displacement between competitors.

If you're trying to make as much "average horsepower from 2500-6500 per cubic inch" which is what this competition is comparing .. then sure. Limit your cubes to get the powerband where need it to win the dyno trophy.

That's a heck of a potent 371ci engine, But with a 4" crank it would end up at 414ci and would've made more overall horsepower at a bit lower RPM

And horsepower is what gets you across the line before the guy in the other lane.
