I just picked up this new small block chevy GK camshaft. This guy had it resting on his shelf for quite awhile, and the lobes are rather large. My question is does anyone have a old General kinetics catalogue to look up the specs for me. The number stamped on the shaft is CIM286B  And there is a couple letters stamped sideway across some of the other letters or numbers  they are Y and S
Thanks in advance

Here is a link to the HotRodders forum..they discuss the cams and their code breakdown;

http://www.hotrodders.com/forum/general-kinetics-cams-17713.html

From one of the responses:

 General Kinetics cams= C.=Chevrolet
 M= Mechanical
 H= Hydraulic
 1= Small block
 2= Big block
 284= Advertised Intake duration with 1.5 rocker
 a-z letter suffix= modification of original design. More exh dur., changed centerline, changed exh pattern, etc. EXCEPT the "R" series of "Redline" cams. These were the "White box" mass produced street cams that you can still buy under a dozen different brand names.

SO if you have a C1H284R General Kinetics cam. You have a Small block Chevrolet, hydraulic lifter cam with 284 advertised duration, Redline series.

 Thousands were sold as were the 292 and the 312 R series.

Thanks Ed.
 Near as I can fugure the cam is for a small block, it is a solid or mechanical lifter style, and the lift would be around the higher 480s. It should be a neat street or strip camshaft. I have a neat little 283 it would be great in.

No problem..guess you know to determine lift just measure a lobe at a high and low point, subtract and multiply the remainder by 1.5 (rocker ratio) to determine lift.  I'm sure that's where you got the 480 lift figure from.
