Mr. Excalibur:
Congratulations on stepping up to a big block powered Cobra.
The reason a "rice burner" with 500 turbocharged horsepower can run so fast is easily explained.
1. power to weight ratio
2. power to the ground (since these car can't run huge slicks, they use low torque to get off the line and then were traction is no longer a issue the horsepower and aerodynamics of the car come into play).
3. Aerodynamics
While these are just a few examples, this is no different than when I ran against a 800+ horsepower Supra with My big block Cobra. I made sure the race started at 35 - 45 mph (were putting down my 699 ft. lbs. torque wasn't a issue) and leaped ahead off the "go" and only lost a little ground at around 150 mph were the race ended. From a 0 mph launch I would have lost due to traction issues, were my heavier 69 Mach 1 Pro Street car (with about the same horsepower as the Cobra) would have easily beat the Supra due to the huge Mickey Thompson slicks.
As far is which is better, depends on your use of your Cobra. It is not the added weight of the big block that makes it harder on a road course, but the extra torque. It boils down to putting the power to the ground. A 500 ft. lbs. torque small block Cobra can go into the turn with the throttle gunned and have the car not go around as easily as a 600 - 700 ft. lbs. torque big block powered Cobra.
