I did a 454 with a TH400 (similar ratios to the C6) with large (255/70-15) tires and it was pretty well matched. The cam was 218/224 with a stock stall in a 73 Impala S/W with 2.73 gears. It wouldn't roast tires, but there was plenty of torque to get you moving quickly and enough "leg" to make highway cruising nice and easy. Perfectly matched? No. 3.08 or 3.42 would have been perfect for that cam and tires, but it wasn't enough of an inconvenience for me to shell out the money for a new gearset for an obsolete axle that was only used for three years.
