bore vs stroke

A shorter stroke will rev faster than longer stroke... But longer stroke will develop more torque at lower RPM...

It's kinda like the chicken vs the egg argument...

That's why it would be a great experiment to build a 340 and 360 with identical components to see how they compare to each other...

Simply isnt enough of a window at higher rpm to feed the long arm. That's the point.

Typo was, while on talk to text, my neighbor asking if the 426 had a shorter stroke than a 440 after i read aloud some replies.

2.1 rod stroke ratio is the thing high rpm dreams are made of... f1
383 just happens to be in the 1.80's rod ratio bracket..
