Does anyone know what makes certain motors able to rev and other makes can only acheive low rpms? if you have a 4.25 bore and 3.5 stroke you would think this short stroke would enable this motor to rev up high but it is known as a truck motor so everone dismisses it and says why do you need to go fast? (duh) Is it just a matter of the cam specs ? The carb cfm? The old ford flathead can now have multiple blowers and run like a scalded cat yet was known for a while as a slug Any Ideas?
