I have the GM Forged crank in my car, and just had it cleaned up and polished by a very reputable crank shop in my area (Moldex Crankshaft in Dearborn Heights, MI). I am having trouble finding bearings that fit the needs of the crankshaft. The crank is undercut .030" on the mains and .020" on the rods. Was also told that the bearings need to be chamfered. The rod bearings are no problem, but I am having trouble finding a "race" or "high performance" bearing for the .030" undercut on the mains. Any help would be appreciated.
