So mark
based on my motor in my Sr 72 ..... than you would expect me to easily hit 13 's range .. assuming my launch is as good as yours !
Like I said, I dont know what hp or torque I am making since I havent had it dynoed. But the Sr 72, unlike your Sr 71, this is strickly a track car.
Were as I think you still have all your a/c controls .. blower motor .. the case under the dash .. mine is gone.
