340 Vs 360

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.

The powerband is fix so larger engine the more potential power between 2500-6500 why they do per cubic it's competition of who build the most efficient engine basically lbs-ft per cid across 2500-6500 rpm don't think smaller is really an advantage.

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.

I don't think it's guaranteed that 414 would done better but even if it did the point was that the more dial in the more everything is designed to work together for particular combo the better the results, that's only at 1.33 lbs-ft per cid.

With off the shelf parts each gonna favor different combo's eg.. they don't make a line heads for each displacement and various bore stroke rod ratios at different powerbands for each etc..
