Hi Don,
Nope never got a chance to use the NOS, found the problem before hand which was good.Saddle's fit snug when installed, seem a little looser now but dont seem to have any side play in them.Its a Factory Steel crank .030-.030 4 bolt main with bolts.The main bearings I could spin around the crank and removed them from the 3 journals that spun but not Rod bearing failures or or any that looked like they weree ready to go.Have only been turning the motor 6600 of late... might see an occasional 7600 in the burnout or if I miss a shift but thats all.
