This is a Corvair matchracer from the late '60s. Basically, too much is not enough. So I'm going to combine a Corvair and the Hurst Hairy Olds. I call this build Unsafe @ Any Speed.
The first thing that I did was narrow the track 12 scale inches, by removing two six inch wide strips from the Olds' chassis. The Hairy Olds used Olds Toronado power-trains. In the 442 body they were a foot too wide for the Corvair. I had to narrow it in two 6 inch strips, because the engine and trans mounts are in the center of several of the eight cross-members.
Next, I shortened the wheelbase 15 inches. And finally shortened the rear floor pan another 11 inches. A tweak here and there and it fits.
Later I had to remove another 4mm from the rear, to center the wheels in the wheel wells.
