Some people at Car shows

Took my Demon out for a drive today and stopped at the newstand to get that Hemmings Muscle Car mag that has the article about Hemi Denny and 62BT409's EL5 Demon in it and a guy asked me if my car had a 3/4 or full cam in it? What the hell does that mean? Is that a Chevy term or what?
I should have told him it didn't have any cam at all.

I believe he was asking if it was a smallblock cam, or one for a 3.9, since they're 3/4 of a smallblock, lol. Actually, this is terminology leftover from hot rodding's earliest days, when there were very few profiles for aftermarket cams. Full race, 3/4 race, etc. Guessing this guy's been outta circulation awhile.
