Greg,
Try a 4.30 gear with 12 x 31 or 33 slicks.
Also try a smaller carb than the 600 if you plan to use a hydraulic cam. And maybe a 5000 RPM stall converter - more if roller cammed. If you are using the 1.82 'glide weld the ends of the pinion shafts to the planetary carrier with silicon-bronze rod to make it live. 300 HP at the rear wheel should get you into the 9.70 - 9.80 range.
Good luck
