A steel Scat 4.250" crank will go to 7500 rpm easily and in a correctly-spec'd engine, will rev like a chainsaw.

If we made the assumption that long stroke crankshafts won't rev, then someone needs to tell Warren Johnson, Pat Musi, and Jon Kaase that they shouldn't be using those 5.500" and 5.750" stroke crankshafts in their Pro Stock engines.

*You need to look at the whole package* before you make gross blanket statements like that. I have seen a 3" stroke 302 truck engine be flat-out lazy and I have seen 5.750" mountain motor pro stock engines go from 1500 rpm to 7500 rpm in an instant.

Before a statement like that is made, you need to look at the weight of the crankshaft, the weight of the reciprocating parts, the weight of the balancer/flywheel and the amount of compression/horsepower/torque that the engine is making.

One of the things that absolutely burns my biscuits is the amount of goofiness that gets passed from forum to forum by armchair engine builders. Stroke vs. acceleration is one of those goofy things.
