Was wondering if anybody might know the specs of this cam, it was in a 1972 340. I found specs for Pontiac and chevy, but couldn't find any for the small block Chrysler! I am thinking it is along the lines of a factory 340 cam, if it isn't the original? But anyway was trying to find lift, duration, and rpm range, at least? The engine has been rebuilt, at least, once!

Super low and mid-range power. Good idle, fuel efficiency and driveability. 4 barrel and headers recommended.

Sweet, sounds exactly what I need, and thanks for the information. That is the lift I was thinking it was, had no idea on the duration!
