Does anyone know what these cams are: 115010320032 ? That is the number, according the paperwork that came with the car I just bought ('76 Alfetta GTV with Ingram's HP pump).

This camshaft is...

OK, I'm pretty sure this camshaft number indicates an official ALFA GROUP 1 cam, with 246 duration, 83 overlap, 10.92 lift (Rank 8L). But, what is a "Group 1" ?

Further, I took the cam cover off and discovered the actual cams in the engine have the number 105.48.03.200.51, and have a measured lift of about 10.55mm. Knowing that the Euro 2000 cam is this number with ".01" on the end instead of ".51", can anyone tell me what the ".51" cam is? Duration, etc.?

The cam numbers are all cast, not stamped.

Should I be using a milder exhaust cam in my Spica HP street engine?

Thanks,

Mr. Goose
