Greddy 7M Cams?

[Alec]

Hey guys, a close friend of mine has a rare set of Greddy 7M cams that he said he'd sell me. He bought them back in 1992 and thinks they're 264's but doesn't have much info on them.

Does anyone know anything about these?
All help is greatly appreciated!

Never heard of the Greddy's, but they probably did since there were Blitz high lift set, and of course HKS's.
He can perform rough measurements to get an idea on their spec's

Does he have any measuring tools? Dial indicator with a magnet base would work for measuring lift if he has a spare head or live centers to hold it and turn it.
