My cheapo 440 in my 68 Satellite was .030 over 2266 TRWs (8.5ish comp) 906s, Comp 292 .501, Torker, 750 vs, 1/78 headers 2.5 exhaust, 11 inch 2500 converter, 3.23 gears. 235/60-14 (about 26 diameter I think) street tires. Had a lift off 6 pak hood. went 13.24 at 103. Opened headers brought mph up to 106. 28x9-15 ET Drags were no improvement due to my poor low end. Stuck in a 10 inch GER( yeah,I know)converter. 12.90s. Weld wheels in front, removed heater/Ac box under dash, made up some homemade SS springs. 12.60s. Traded my 750 vs for a 750 dp, added one inch spacer and with some nice cool air. 12.35 at 107. I'm guessing your Charger weighs a good couple hundred pounds more than my Satellite. I think the thing that will hold you back the most is your converter. My guess: 12.95 at 110.
