I have broken 2, although mine were 3.875 stroke
snout on both broke behind balancer, bolt still attached to piece of crank snout left in balancer.
the bolt is too short that holds on the balancer in my opinion (it is stock GM length)
My Callies, and Lunati both are 4-5" long bolts, and have never had a problem with any of them.
May be ok if you go with the big block snout option, but I will never buy another one.
I think there should be lifeguards in the genepool.
