Comp XE268 - O/T, Brand X!

I ran that cam in my 64 chevelle years ago in a 350, although i had AFR heads, a moderate converter and 3.73's. I ran 13 flat although more converter and traction would have had me in the 12's easily. Great cam in my opinion but remember that it clicks more than conventional hydraulics - don't overtighten your valves thinking they're loose!!! Good luck!
