The older parts weren't designed with current computer or manufacturing technology and generally are weaker. If it wasn't NOS it could also be subject to corrosion, high cycle fatigue, and cracks or stress risers from mishandling or misuse. NOS could still be subject to corrosion (at least parts from the 30's are).

If Keith and Barry agree exactly, it would be very hard to argue any other result. This is a very important quote: "I have used these in engines over 700 HP for three years now with zero broke."

The prices Keith listed are very reasonable, especially from a shop of KCR's caliber.

BTW, did that include balancing, rings, and bearings?
