Well I have one question my wife is wanting to enter a sled pulling contest next year and of course it will be our first run. We have a 1988 F350 7.3 idi zf5 transmission all stock except she has 4 door flatbed and the class she wants to run is of course stock. She said for her run she is looking at 2nd gear all the way since 1st is granny gear and 4 low not 4 hi. Our question is has anyone seen a 7.3 non-stroker run and what can she expect off the run. Honest opinion would it be a total loss to enter this truck all stock?
