I'm going for the 5ft. trophy tonight. It will be my first mud race and I'm very excited. I've got my truck set up how I want it for the most part and now it's time to tear it up. I think I'm going to run in 4-HI put it in 2nd gear and stand on it. It will either go or blow! The "strip" is about 100 yds. and 2ft. deep with some deeper holes depending on the lane. If I keep the tire speed up on my 78'(355cid with 36" swampers, 3.08 gears and 4-speed) I might have a shot. Got my 15,000 lb. snatch strap wrapped around my rear pipe bumper just in case!
