Almost a year later and I finally have the Charger back on the road. I went with Hughes hydraulic rollers and am very happy so far. It's very quiet (no tappet noise) and responsive. Over 500 hard miles so far with no issues. I won't have it to the track for a while yet, but I know that it will now be well into the 11's. The cam is Comp's XR274HR-10 grind, Part # 23-710-9. The idle is still a bit lumpy, but the vacuum at idle is 13.5" in neutral and 10.5" in gear @ 800 RPM. WOT is pretty crazy, my 275-60-15's are nowhere near enough tire. Street manners are fantastic, I can use overdrive at 30 MPH and can lock up the converter at 45. Will post true MPG numbers after our first cruise next month and real ET's after the track runs in early August.
After talking to a bunch of other engine builders and Comp roller lifter users my advice to anyone is get them out of your engine NOW if you are running them. For anyone thinking of buying them the very common answer is: DON'T!
