Skuzzy,
That 576/543, is that engine or rear wheel numbers? either case with a 2200lb car that's got to be pretty insane . Wish I knew you were a car guy at the convention last year, would of loved to talk cars I'm all the sudden thinking my vette needs to go on a diet or bigger blower

That is the engine. No car to put it in yet.
Most of the Cobras, in the lot I hang around with, have engines that run from 500 to 650HP. There is one with a stock 302 in it, and another one with a stock 351C in it, but the rest are pretty much over the top.
One guy has a Hennessey Viper V-10 engine in it (around a 1,000HP). Another one has a BWM M series V-8 in it.
The problem with the high horsepower is getting a decent launch. However, those cars also have no problem parking the speedometer at 185MPH for hours on end. 185MPH is considered to be the safest top speed for a Cobra, due to the lousy aerodynamics of the car.
There is a video of a Cobra running down a straight away at 180MPH, and the rear end lifts enough the tires start spinning and smoking. The driver shed a few pounds of poop when that happened.
