Karl, they do. But they use Fox bodied Mustangs with twin hair dryers. I grew up on Chevys and they are just cheaper to build and parts back in the day were easier to acquire. I adapted to this car/motor...still has 8 spark plugs, just a different firing order. With all the SB Ford development as of late, it's only a matter of time before someone does what Colin has achieved. Just most people going that fast prefer to have a roof over their head!
