Those numbers are so ridiculously useless its not funny.

I would love for someone with a proper GTR cam to actually Degree it for us and give us something useable, same as a XU-1 owner.

The challenge has been laid down, can anyone come up trumps?

Cheers.

I agree Bomber , but unless your going to grind your own cam ,or are in the trade , for a small street cam it's good enough .

No, its not.
Those numbers depict about 500 potential cams.

I only want to know out of curiosity.

Thiugh i would really like the specks for hb series 70 and brabham.

I rang Ivan's Cams today , and was told they only have two small Holden cam regrinds available , one , he said would have been the 186S and the other he thinks is the LC GTR . Maybe they can help you GTR-1.
