Again, sir, let me explain your own statements to you, since you are incapable of understanding them.

Most racing sanctions have rules. They are limited by displacement, either by the bore or by the stroke. Think Formula 1. Think NASCAR (358 ci rules).

When you are limited by displacement, then you *have* to turn the rpms WAY up to make horsepower. That's why Cup engines have to turn 9800 rpm. That's why F1 cars have to turn 12000-13000. When you only have bore and stroke to work with, then of course you make the bores large to help with head flow. When you don't have displacement rules, then you make both big.

Another reason for the short stroke on the Cup engines and F1 engines is because it's easier on parts. A smaller crank is going to be easier on bearings, and a short stroke will be easier on the pistons/rings/etc. because the piston travels a shorter distance. When you're racing for hours at a time, for 100's of miles, sometimes you do things for longevity. When you're drag racing, then you see what MAJOR race shops do.....add lots and lots of stroke.

You are incorrect in pretty much every statement you make. Of course you don't intend to be, you just don't understand things. That's why you cut and paste from Wikipedia and I go out and look at dyno sheets.



Have a nice night. I'm gonna shake the dust from my feet on this one.
