You usually get the same HP with either stroke and the bigger the stroke the lower the rpm it will happen.
I like that you can make the same power at more reasonable rpm levels. Just my

but also higher piston speed.



You're right but think about it like this.. Let's say a 4" stroke makes peak power at 6500 rpm that's 72.2 ft. per min. Now put a 4.250" stroke in it ans say it makes peak power at 6200 rpm, that's 73.2 ft. per min. Not much difference huh. Will also have more torque to get the car moving. Less convertor and gear needed.

Very true MORE so in a 360 Main
