[quote=CNC-Dude #5585]A previous owner would have had to have done it or perhaps a mechanic, no Chevy 6 cylinder crank was ever drilled from the factory. Even the Stovebolts going back to 1937 or 38 were not drill either. [/quote
Not quite true. All 292 are drilled for the snout bolt. I think a few 250 were. But all 194, 215,230 and most 250's were not drilled.
I did suggest his crank get drilled and tapped after he pulled the cam. Maybe Gbauer did not read that. That bolt could be used to turn the engine.
