Any ideas of camshaft manufacture and spec? its solid lifter rough measurement of .530 lift ..it scribed 285-295 and 108 as well as the other visable numbers

hope the pics are good enough, thanks in advance

I'm not to much help but that is a comp cam. the c over c denotes that. See what they list at those durations and lobe center.

Looks almost like a regrind to me. Like comps old way of writing and mopars way of stamping.

I agree with that also.

its a bb 3 bolt, it does have a cc on it also, 285-295 any rough ideas duration at .050

thanks for your input

probably something like 250/260 just a guess I could look at my cc lobe catalog tomorrow. Looked like there was a serial number on it maybe they could look it up.

there are several options on how to find out how this cam is ground now, mock it up in a block with #1 or and #6 pistons and two solid lifters with a degre wheel on the crankshaft and a TDC indicator and rotate the motor around with a decent dial indicator reading off the intake lifter and record the readings at .050 lifter lift before and after TDC, then check the lobe separation angle on that lobe and then do the other exhaust lobe the same way.
The other easier way is to take that cam to good machine shop or speed shop that has a cam checker and have them check it and give you their results

285-1/295-1 S108 is a Comp Cam utilizing the “High Torque” series of lobes.
It’s 250/260@.050 and has .355/.370 lobe lift, and is ground on a 108lsa.

The lobe catalog shows them to use .018 lash, but those are some of Comps earliest lobes.........and “back in the day” the recommended lash was .026”.

Thanks for everyone's input..the good is it's probably a good core that shouldn't flatten a lobe
