Roger Simon's 1976 Trans Am
(In His own Words)

Roger has been a great customer for a lot of years, he sold this car and managed to get it back with some upgrades over his old combo.

First shake down outing netted a 10.37 @ 130+mph almost 131mph in LA with 85 deg high humidity conditions, Roger is confident there is more in it and figures it should have no issues running 10.20's or quicker with a bit better weather and more tuning. (only 5 passes so far)
4500 stall 3.73 gears with 28 X 10.5 tires, 3500lbs with driver.

Performance Update 10.16 @ 133+mph

Note: This is on the motor no passes with the NOS yet
