if the weight is with the driver it should run 9.80 at 137.+ MPH once sorted out with open headers twocents
My old pump gas Duster ran 9.993 at 134.8 MPH corked up(3.0 inch exhaust system to the rear bumper) on pump swill with a 518 C.I. 400 block stroker motor with a little less compression weighing 3450 lbs. with me in it. IHTHs up
