John,
That's the most you would go on a weldup stroker?
I wouldn't spray it at all quite frankly. you could put a 60-80 shot on it though.
Some people spray the hell out of them.
Some people try to say the welding is just as strong as a forging or billet as well (which could be possible IF the whole crank was post weld heat treated, which is not done)
Even prominent crank resellers will not recommend a weldup for big spray.
