HR means hydraulic roller,and I'm assuming the T in front of 3389 is for their "Thumpr" cam series. That's all I've got.

That is typical Comp Cams nomenclature... The CC is for Comp Cams.

The 3612/3129 are intake/exhaust lobes and HR10 means it's a Hydraulic Roller ground on a 110º LSA.

I found the intake lobe, but can't find the 3129 exhaust lobe...is it for sure 3129?

Cam looks like this so far:

224º/xxxº (@.050) 276º/xxxº (gross duration)

.512"int./xxx"exh. with 1.6 rocker
