Thanks! I'll probably be measuring the actual specs on a series I camshaft soon myself also. Thinking about putting a custom cam along w/ some other things into a series I engine later(NA buildup).

There are a few people on the bonneville forum that have all the specs for the cam, like lift, lsa, duration, etc.... But, its basically almost the same as the Series II cam...the series II cam is like .255/.258, just a little bigger than series I. I think it has a couple more degrees of duration too.
