I would guess that you do not know how to degree a camshaft.
I need to know where Comp recommends it be installed, .... INTAKE CENTERLINE, ITS ALOT EASIER TO READ IT OFF THE SPEC CARD ,

From those numbers, that does not appear to be a Comp Cams camshaft. A comp grind number would look like 4012s/4012s R108 or something similar.

basic install on most is split overlap.

if you knew how to use a degree wheel, and could determine the lobe seperation angle, then there is basic math involved to determine the basic starting point of intake opening and closing along with exhaust opening and closing.

if it is 35-772 it is solid roller xr286r adv dur 286 in 292 ex @ 50 248 in 254 ex lift .614 in .621 ex with 110 lobe seperation
After looking closer it appears that it may say 35-772,but again that number is barely legible, it is definitly a Comp stick,but with those other numbers i 'm wondering if it has been reground or a custom grind from Comp.I havn't called Comp yet,hopfully tomorrow.THANKS

o.k.

but it seems that you have spent more time on this site / internet than what it would take for me to run the numbers with a degree wheel and figure it out...!!!!!!
