I knew a guy who built one of those Cobra kit cars. The originals are way too expensive to own. Anyway, he built it as close to one of the originals as possible..
427 engine
411 gears
But he put a 5 speed transmission in for the OD feature at highway speeds.
He took me for a ride, and the entire time, my back was cemented against the back of the seat. I was frozen there and couldn't move from the G forces. I can just imagine what jet fighter pilots must feel!
It made my 427 Camaro feel like a tinkertoy!
