Are there any stroker cranks available? I've heard of them, but can't say I've seen one. I've got an extra crank and have been daydreaming about what could be done with it. Anybody build their own stroker cranks? Im guessing with some welding and machining it could be done. How much can they be stroked? Do you have to run a spacer plate or a shorter rod? I'd like to see a good thread on 250 strokers
