As folks here already know, I've acquired a dual Weber 40 setup and will be going down that path this fall as the weather becomes more conducive to extended garage sessions here in the Phoenix Metro area.
With my '78, I'd like to get a little more "breathing" duration with the early cams to exploit the available flow from the Webers. I have scanned the archives a bit, but didn't see anything about distinguishing marks on cams. Or heads for that matter. The most resolution I've seen is engine case castings.
Sorry if this is common knowledge, but if I run across "loose" cams, how can I be assured they're early ones?
