He gave me his card and said "young fella when you get ready for a cam for that thing give me a call". When I decided to build the 95 HP combination in 1976, I called Lunati. Two weeks later I received the cam. It's been in there every since.

Tom....those cams were like the older jr. stock days up until 1972 when they had to run the OEM cam when everyone went to S/S.. Your correct in that they went back to "Blueprinted" cams or "rate of lift" cams in 1975 because NHRA could not police the OEM cam rule. Then in 1985 it was anything goes as long as the lift checked.
