Offset Grinding a Chevy 235 Crankshaft for a "Cadillac 261" Stroker Engine Build 

I'm using our Storm Vulcan 15AW crankshaft grinder to offset grind this 235 Chevrolet 6 cylinder from 3.940" to 4.125" stroke. Crankshaft was chevked for straightness beforehand and the harmonic balancer bolt was drilled and tapped 1/2-20 as well. Engine is going into a 1952 Chevrolet 2 door.
