[Cool Kat with Hot Car]

Just dug out an old hot rod flathead I have had sitting around. It was built in the early 1980's. It looks to be pretty stout with a 4 1/8 Merc. crank, real beefy front and center main caps, lots of work on intake ports, etc. It has a cam marked Potvin 3/8. Can anyone provide the specs. for this cam?

Thanks
