Crank is shot, do I stroke it or not?

Sorry Brian, I respect the hell out of you, but with that cam and head combo you won't get "a lot more torque". It will make peak torque a little lower in terms of rpms, and even that won't be overly dramatically different without changing the cam at least. 10% more stroke will drop a few hundred rpm, but a 360 with that cam makes great torque right off idle. That's really what we're talking here. Lighter internals won't mean **** with a 30lbs flywheel and mild gearing other than it will rev higher. Run the 360, and stick an aluminum flywheel on it if you want it to rev faster.

How can I say this...uh....your wrong. At 2000-2500rpm the 4" crank will be up about 30-40lb.ft. more and still make more at peak and past peak.
And yes the lighter rotator will make a very noticeable difference. You just have to know your way around these things!
I do have ways of measuring output...I'm gonna leave this one alone as once again naysayers would like to stir the $hit pot :wack:
