Quick comments off the top of my head(ers?):
1. Bullet lash specs are given for the lobe, not the valve; multiply x rocker ratio, plus add .002" for exhaust lash

2. I heard recently Engle has closed its doors, so don't get too set on one of their cams.

3. I run a smaller Comp XX 298/266 grind in my Challenger. A Comp tech rep (one who actually knows something) said I could run it from .016-.024". I think the XX has better RPM capability (and probably better reliability) than the XTQ.







I told to Engle this AM, so they are still open..at least today. LOL.

I wasted 30 mins or so on hold waiting for Comp this AM. Finally got through and the guy told me the XX and STQ lobes are way too violent for street use. I knew you were using the XX, so I didnt argue with him.
