"Tip of the iceberg" on cheating.....dirt modified: I went on a diet and lost 30 lbs, we used thin wheels on the right side, aluminum brake drum and weight jack bolts. inside the left frame rail was a 40 lb section of lead. used thin wall tubing on right wheel guard. All of these mods resulted in a 5% left side weight gain. Nitro in the radiator side tank, ran a Teflon "wire" to the intake and dashboard, turned it on by rotating the gauge. Tech did not like the wire running from the radiator....Cut the right front brake pad down, after a couple of laps it would glaze and not pull down the right front entering the turns. The back panel was suppose to seal off the air, ours looked that way but we had a second cross tube that hid a 3 inch wide gap. Asphalt limited late model: off set chassis, cut heads and block, cut out the plenum on the intake, cheater cam using a stock reground cam, left front shocks that were solid, never checked our welded rear end. vega torque converter to save weight. modified carburetors and distributors.......names ground off soft compound tires. running a full windshield and opening up the "fake" hood scoops, bending up the rear of the hood, rubber flap on package tray and flaps at the rear of the trunk all for areo advantage. 1975 to 1990
