Dynamic comp on 390

not @ 050" only at .006" as I posted.

Sorry, my bad. Thought I read different.

The advertised numbers are 292/300 but at what exact lift point Comp uses for that XE Hyd roller shaft is IDK. You could try those numbers. I’m not 100% on this, but *I Think* Comp uses the .006 on there other cams along the similar lines. As in not there race cams.

Xtreme Energy 242/248 Hydraulic Roller Cam for Chrysler 273-360

I see your location. Perhaps a phone call would work? I know the time difference is huge.
