I'm sure your setup runs very good, but if this is a street car, 3.91's or 4.30's and a cam with 250@.050 duration (like the 508 has) in a near 4000 lb car (3rd gen charger) is going to suck doing anything but WOT 1/4 mile at a time....you'll be cranking along at 3500-4000 RPM to keep up with traffic on the freeway in MN, it'll be a dog at part throttle, etc.....

all depends on his intended usage for the car...
