Whatizit SBC roller camshaft #1

First of two small block roller camshafts in the pile of goodies I picked up. One end has been hand marked as follows:

 

312-5

322-3

WR7

N9751

 

The first two numbers loosely correspond to various Comp Cams SBC offerings, but also tie into a Hemi camshaft. The other numbers are question marks.

 

These speed parts were used on (or kept as spares) for the cars Jeff raced from 1977 through 1987 (particularly on the 1982 Camaro below, I'm told): www.racingsportscars.com/driver/photo/Jeff-Loving-USA.html
