Sorry Mike,I forgot to mention that he put on 9 inch goodyear slicks. [d-5]compound! The logbook the guy kept on the car was incredible. He monitered everything from barometric pressure to the heat of the track every time he went out! Airbags in the rear springs [8lbs on the left 15lbs on the right].LAUNCHED IT AT 6000 AND SHIFTED IT AT 6400 BECAUSE HE SAID IT MADE NO MORE HORSEPOWER AFTER THAT] AND THE CAR STILL HAS THE ORIGINAL BLOCK IN IT TODAY. The car ran a miserable 1480's on the polyglas tires.
