for me -- C -- is the barracuda ( 207 ) cam and if it is this is wnat it is if you know how to check it you can confirm what i am giving you
32 56 duration = 268*
X add them plus 180* @.053 lobe lift X rocker ratio = .336 x 1.43 =
57 31 Duration 268*
The total cam lift is .480 total lift at the valve - max spring travel coil bind .510 its set on a 102.25 lobe center
TDC lift < valve to valve info - intake .157 -- exhaust .147 you need .060 between the valves @ over lap - can be checked using sparkplug hole -- not easy tho
its a high RPM cam with very strong bottom end and good transition to a powerfull top end --johnjzjz

Still Trying To Identify Cams 1965 Sportster
Thanks for the info sent, but I couldn't get any of the links to work for the Sifton info. I've attached pictures of the cams I'm trying to identify from my 1965 Sporty. The markings are as listed in my earlier posting.

tom sifton was a simple Man he did not get into big long part number the cams are marked correct for a 207 with the location of the cam 1 2 3 4 - wirth a C following each number i have an old sifton book and no pictures are really in it - the 207 shows up no place on any of the C cams he made = hope that helps - the best cam he ever made was a minis / minis - he also had a plus minis but the minis minis was the hottest cam he ever produced - the fake V Twin copy are garbage
I do not understand why the links do not work for you. I have posted them often with no problems. They link to the Public folder on my SkyDrive account. There is lots of info there, if you can get them to work.
What happens when you click on them?
