Anthony,
The original 427 C3 AA Cobra Cam was in fact more duration than the Comp Cam in this thread. It was advertised at 306. The comp is advertised at 294. That's a difference right there and remember the Cobra's made about 480hp back then.

From what I remember, alot of the "factory" cams had a large advertised duration, but the duration @.050" was relatively short for the given advertised duration compared to afetrmarket cam specs, as the factory cams seemed to have a more gradual ramp. I'm curious, I'll have to see if I can find out the factory cam spec adv duration vs. duration @ .050" which, from my reading is a more reliable indicator of a how radical a cam is. So even though the comp cam is listed at only 294 duration, it wouldn't surprise me if the duration @.050" is actually larger.
