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.
