Camshaft Origins

[D HALL <dthall@btinternet.com>]

Hi
  Just wondering if any  has heard of a camshaft SID1 or SIDI that is the 
number on the container. The camshaft that is in the container I believe is a 
std cam for the 3000, therefore the racing cam is in the engine cica 1977. The 
cam, according to the container was purchased from Gran Prix motors of High 
Road South, Tottenham, London. Any knowledge of this cam. Is it a full blown 
racing or a fast road cam?
  Thanks in anticipation David Hall
