with a stock bottom end 383 in my charger, stock 906 heads including springs, DP4B intake, 850 T-quad carb, SSH-25 hydraulic cam installed straight up, 15% initial, 36% total timing, B&M hole shot converter 2600rpm, home brewed shift kit, 3.91 gear, 27" street tires, and 4000lbs plus, shifting at 6000, my charger runs 13.95-14.15 depending on the air.
just a comparison for the OP to consider for tuning upgrades.
