Re: GM Cams
I believe it's the exact same cam. Same specs, same casting symbol, just different part number.
It's listed as being used in the L-78/L-71 in '67, the L-78/L-72/L-71 in '68, and the L-78/LS-6 in '70, but in '69 they changed the part number for the L-78/L-72/L-71 cam, even though it had the same specs in ALL the years?
