Subject: [alfa] Camshaft info?
I recently purchased an 2L engine for parts. To my pleasant surprise the
cylinder head was ported with oversize valves on the intake side.
The camshafts are marked 306 on the ends. Can anyone identify these
cams? specs?
Thanks

I purchased mine from International Auto Parts. It is their 300 degree
11mm lift cam that has had various labels applied to it depending on how it
is set up (valve lash and lobe centers). They have been sellig it for a
loong time. Currently advertised as #92650 "carbureted peformance" with a
.014 valve lash and 102 degree lobe center. When I purchased mine 20(?)
years ago, it was called the "40-80" cam with 110 degree lobe centers
recommended. I ran them at the 102 lobe centers and tight lash, with good
results. However, at one point I acquired a set of Euro 10548 cams, and
split the two sets up such that the IAP cam was used on the intake, and the
euro on the exhaust, so I had two high performance cam sets. This
combination idles better, has better low end, and better fuel milage, but
maintains the high end power provided by the IAP cam.
