No way the 600hp 340 wins over a 600hp 540 because while at one point they both make the same power, the 540 makes the power over a longer period of time. Granted the 540 may make so much power early in the rpms that it can't harness it to the ground but just building a motor for peak horsepower with no regard to overall rpm horsepower is not going to give you the quickest 1/4 mile times.
