Has anyone broke a stock LS1 crankshaft ?

Stenod Perfomance has a couple guys pushing 1400+ on a stock crank, I believe Ohio Boys are also running a stocker in the 7's (1/4 mile). In fact, I don't know if I've ever heard of a stock crank failing before..

I ran one for two years (well over 300 passes) in my 347 and I'm running a stock (6.0L) crank in the new LS2 I just put in. Matter of fact the crank that was in my 347 was a well used crank out of Distortion_69's M6 car.
Crank and bearings looked fine when i took the 347 apart. I dont think I would use one in a 8000+rpm 1500hp setup but these are some pretty tough little cranks..

Depends, if you dont have a crank buying a new OE one vs an aftermarket one isnt a huge difference so I would buy aftermarket if I was starting from nothing. Pretty easy to find good used stock cranks cheap though. Like anything else it depends on your budget and power goals..
