I talked to Jim at Racer Brown about it when I ordered the cam for my 273. He said he could duplicate one if he were to get his hands on one. He's never actually laid eyes on one yet. He's got some cam's that he think might be close.
They were originally ground by CamCraft, but when I contacted them to see if they could grind them, the answer was no one knew the spec's todo it.
Oregon cam grinding said that they could do it if they had the overlap as well, Ive known the lift and duration for years but nobody seems to know the overlap
