I was told that I have performance cams in my 1974 spider that I just bought but all I can see is the number 306 on the very end of both cams so can anyone help id these or tell me how to find out please.

306 stamped cams have been up before.....no real conclusive evidence what they were......
camshaft identification
possibly Alquati, for which see:
Cam shaft idenetification

Post pictures of the lobes. Measure lift

I will do that today sometime. I am wondering if I have larger valves as well, Can someone give me the intake and exhaust diamiter in stock form?

Intake valve approx 41mm diameter and exhaust is 38mm and looks to have a 11mm lift and only says 306 on the back end of both cams.
