Is this the norm or did I get a bad one? 440 stroker crank, 4.25" stroke, 2.7500 Mains, BB Chevy rod journal size - 2.2000"
All mains are undersized...none measure 2.750" and some are .0007 - .0008" too small
the first 3 rod journals (starting at the front) are spot on at 2.2000", the rest are all undersized...some as much as .0008"
I don't have the notebook next to me to give the exact measurements, but damn....not really what I was expecting from a brand new crankshaft.
Any similar experiences? or is this a fluke?
My Callies crank measures between 2.7491" and 2.7494" on the mains and 2.1993" and 2.1994" on the rods. Doesn't seem like 0.0007" or 0.0008" under the nominal would be out of line?? I wouldn't expect the journals to measure right on the nominal dimension.
You might have to use half of an 0.001" under or 0.001" over bearing to get the clearances where you need them. I can't remember the last time I built a motor only using one set of bearings. I have a shelf of left over half shells...
