Just looking for a few idea's to start somewhere as to why my car runs off so much out of no where. Saturday it was in the 13.69's 2 time trials and first round, 2nd round came along and it goes a 13.637. Also when the car picks up it seems to be all the way down the track not just at the 1/8 mile or 1000" .Tire pressure is the same front and back stage the same shift at 5k 2nd and 3rd. I'm stumped on what to look for at this point. It's a 73 challenger 340/727 650 holley carb, edelbrock performer rpm intake other than that it's a stock motor (#'s matching actually) Any idea's would be much appreciated.
