so building a cast crank 225 limits your rod selection as the 1.21 forged big end width seems to be the only K1, Molnar or Wiseco rod you can get now. .940 width rods are out of production/ sold out?
Cast crank blocks different? You
were thinking correctly..."The cast crankshaft uses a different block..." what difference is, maybe this:
"...Cast crank mains were more narrow also. Maybe the block webbing reflected a more narrow main.
"..Early (forged crank) main bearings are 1.027 inch wide (26.11mm)
Late (cast crank) main bearings are 0.881 inch wide (22.38mm).."
<<<PS. the hydro lifter block
may have been cast 12 lbs lighter, but the rear cam bearing being changed to fully grooved is obvious. Slantsix Dan may have more info on block changes...>>>
