Starting (maybe) a 292  (312 crank) stroker build.  How is best way to check mains bore alignment. Cook book says lay a straight shafting in bearing bore and use a .0015 feeler gauge to check. Or put crank in with new bearings and  check for to tightness. Since I dont have a large straight shaft would a camshaft work? Iam also concerned if line honing  would throw off center line for oil seal, or Iam I buying trouble? Thanks for any advice   Bill  Oregon
