Quote: ......................My 4.25" "B" crank from 440 Source had .0015" taper on all 5 mains; the crank snout was off .001", the rod journals were straight, but the radii were so large I had to make some pretty heavy cuts on Clevite HN (narrow) bearings.
My crankshaft was a lightweight piece with the pendulum-cut counterweights (extra material removed from counterweights near centerline of the crank) and scalloped crank flange. Looked fairly well finished for an inexpensive part.

I used one of those cranks too, and the indexing was off .035", so I sent it back (since it couldn't be offset ground and fixed) and got another.......Did you have your indexing checked?
BG......Are you going to check the indexing on that crank?
