The GNX was the only McLaren /ASC Grand National. They easily did mid-four-second 0-60 times. Those who doubt should find someone to take them for a ride in one. Wicked fast.
FWIW, Menard used basically stock turbo 3800 blocks in their Indy cars.
Today is 07/07/07, and the first GNX I ever 'met' was chassis number 777.
