One of our kingpins is Gerry Driscoll, Mt. Washington speed record holder @113 mph. JD is known for his big block Chevy./automatic trans combination - just like the Chapparal! What is not well understood about this combination is the driver skill required for downshifting - a mis-timed downshift will spin the car just like a yank on an E-brake!

I'll be posting a thread soon on America's F1 - the "Monsters of the Midway" ISMA supermodifieds. The fuel-injected big-block Chevy engines are similar to the Chapparals (and McLarens) of Can-Am, but they gulp methanol now and produce 880+ horsepower. Their wings use technology long since quashed by FIA - like the Chapparal, they adjust downforce for accelleration or cornering - some put the downforce directly into the wheels, as did some of the Lotus F1 cars.
