If there's still no satisfaction, I can break out the H-O catalogs.

just looked at a 1978 catalog.
more info in my post #67.
from the links above, i think there are probably way more
h-o specialties cams than we know about. i really don't know.
my cam came as hc-02. no a, b,c,d suffix.
the numbers i posted above are with 1.50:1 rockers.

I think I have 3 versions of the catalog, last one I think was like 88 or something. Maybe later I will dig them out, now I'm curious.

I ran H-O cams in the 80s in a number of engines/cars, think I tried a lot of available cams back then, H-Os were some of the ones I had success with. One summer I remember swapping cams like 6 or 7 weekends in a row. I had shelves of them, most were junk.

Lunati, Crane, and H-O were the ones I generally ended up sticking with.

Here's one of the Crane Hi-Intensity grinds that I liked to use with 400, as well as the next step up in the same line, would have to dig for that card.

My HC-02 cam is:
301-313 Adv. dur.
231-243 @.050
113.5 LSA

I don't remember the lift numbers off the top of my head but I do recall HO called this their "744 hi-lift cam".

IIRC, Ken Crocie said there were several (4?) versions of this cam all with slightly different specs.

I bought this cam back in the late '80s and I'm still using it. (With Rhoads lifters.)
