It's an old grind, apparently made in the 70s. From what ive read, it was remanufactured and renamed "cruiser", or re-101 when the crappy Chinese siftonss were being sold. Those sucked. I had one, cant remember the grind, though. It was ground off-center. Guess how much fun that was to try to time, until I tore it down and figured that out.
This one is an original sifton from the 70s. Should be a good cam for my needs.

From what i have read, the cam was originally the 55q, and, I also read in a couple places the cam was developed for the chp to help acceleration from a stop. Also read it was a good cam for heavy bikes and two-up riding. Then, it was renamed the 101 somewhere along the line. I dont think it is being reproduced now, at least vtwin and jp don't list it.
Nightrider lists the specs for a re101, and i found another site that has the specs for original grinds, with the 55q listed. Identical specs as the re101. A lot of this cam spec stuff is new to me, ive been reading and reading until i fall asleep haha.
The can I got is stamped "55q" on one lobe, " b t" on another, and "77" on the cam gear. If I recall, the crappy Chinese sifton I had actually had the stylized sifton logo on the cam gear.

The one I got is a 70-early 77 gear, I have a 74, so that should be good to go.
I read some folks saying the cam is for solids, read some guys used them with hydraulics with no issue. The guys on the shovelhead.us forum said because of the low lift, hydraulics will be Okay. Also read around, and found a few separate threads on some forums talking about how solids on an oe "h" is hard on the valve train, so I'll br glad to get rid of that. Plus that h cam I have looks kinda...weird. Not in good way either haha
