      If it helps you for highway specs, I'm running the same ratios in my F-body T56 with 4.10 gears & 335/30/18 rear tires. At 80 mph it turns 2100rpm. I think 4.10 is perfect, but 3.90 would work. The more duration with the cam choice, the more gear the motor will like. Look at the operating range of the cam you select, and choose the gears accordingly.
