My guy finished up a 392(5.7 based) last week , set of Pre Eagle heads 2.125/1.62 valves , 10.5 to one, Prefix single plane intake , HUG SER3438MHLN-10 .589/.594 234/238@50 pulled 55Xhp and 56Xtq at 3600lbs that should get you where you want to be. with good Eagles I would think it would be in the 57X+hp range.
