Hi guys! I have a 1995 ford f150 5.0. I'm entering the mud drags at my fair this year. Should I run my truck in 4x4 high will I have enough power to spin them or should I run it in low range? What things should I do to have a better chance. And I have 32.1150s and a 4 inch lift. I will be in the stock v8 class should I do OK against some other stock v8s?

 

Low range for sure. That 5L engine and tall tires need all the gearing it can get. I hope it has at least 3.55 gearing. I would not expect miracles with the combination you have.

 

I would go high range. Low range tends to overpower your available traction in mud. I had 32s on my 90 F150 with 302 and 5-speed with 3.55 gears - it pulled em just fine.

 

Sounds like fun! What type of mud is it? What kind of tread is on your 33's like all terrains or mud terrains?

If you have all-terrains then I suggest 4H to keep the tire speed up which will keep the treads clear. If you have an automatic then DON'T leave it in OD or Drive because with enough wheelspin it will shift into third gear and just bog down the truck at that point. Start in manual first, shift to manual second if needed to keep from redlining the motor. Pedal to the floor or just off the floor enough to keep from redlining. Well actually you'll get a feel for it as you go, you sometimes only need like 3-4K RPM's but it depends. I suggest you find a mudhole and a buddy with a truck (to pull you out) and go practice a bit first.

 

Another vote for 4-hi... 4low is only good for rock crawling and yanking stumps(or Chevys) out of a hole... just not enough wheel speed for mud or snow IMO.

 

My 5.0, 5 speed, 3:08s would do better in 3rd gear Lo range. But with an Auto trans I agree Hi range. The 1356 transfer cases hi range is their weak link.

 

I have bfg mud terrains. And thanks for the input and I think I'm putting headers on so that will help with power a little bit.

 

What do you mean? T-case hi range is just direct drive/no gear reduction. The 1356's weak link is the oil pump.

 

Its like a thick mud its not clay or anything they just water the dirt.

 

For mudding you need lots of wheel spin, stay in 4-high.

I seen a few xfer cases blowing up in 4-low while mudding with engine red-lined. And that was with both Np and BW xfer cases too.

 

Yeah low range I can understand, the planetaries probably can't take the heat from sustained high speed running and seize up.
