runnin mud - setup

[jeffaj01]

I'm trying to build a fun truck for our local mud run. I was wondering what you guys run as far as tires, running gear, etc. I've seen several trucks running a skinny tire in front and a wider tire in rear, what does this achieve? This is not a pit, but more like a cultivated portion of a muddy field. I bought a 79 k10 with a 350, unsure of trans with a 203 tc. It's had a body lift and 33's put on

In general skinny tall tires with the right gearing will go through mucky watery thick mud, bigger ones usually get stuck.

You will want to run mud tires that clean themselves. For mud avoid all terrain type tires. Thinner tires will dig down quicker to find you better traction. Wider tires will try and stay on top. They also need to move more mud to find some traction which means they use up more horsepower. Don't forget to have good mounts for recovery straps. It is important that your truck not get damaged being pulled out.

Have fun with it at the mud runs! When you get addicted to it then we can help you with some serious upgrades.

Trying to attach a pic of the truck, hopefully this works. The front driveshaft is out of it, and I'm guessing it needsa transmission, and maybe the tc looked at, I tried to move it yesterday, and it wouldn't move at all, but I have driven it down the road before, so I'm confused at what happened in the 3 weeks it sat in my driveway that would cause the tranny not to engage.

I'm not sure which direction I want to go just yet. I want this to be cheap, and I am not going to cut It up at all. I love these trucks too much to murder the thing. It won't be driven on the street, except 2-3 miles to get to the mud. My 7 year old son loves this truck, and is a big drive on my working on it.
Down the road I would like to put a big block in it, but that's wayyyyy down the road, unless the 350 takes a poop sooner then I expect. For now I just want to have fun, and be somewhat competitve. There are 4-5 73-87's that run this mud sling every year, and some do quite well, while others just don't seem to do so great.
Any recommendations would be great.

I cant get the picture to load, keeps saying file is too large, I've cropped it several times.
If you know how to help with the picture I'd appreciate it. I'm working off of a smartphone - no computer.
Looks like someone was trying to work on the truck a bit, new front calipers, new exhaust, a lot of new vaccuum hoses. Overall it runs good, but when it did drive it had a tendency to spit and sputter when I hit the gas a 1/4 of the way down or more. I'm guessing Its starving for fuel the way it was acting.

You said it has a 203 transfer case. With the front drive shaft out of it you have to put it into hi-loc or lo-loc to make it move.

[jeffaj01]

I did get it to go into gear in hi loc, drove it around the yard, but It kept popping out of gear (transmission?) and all it would do is rev. It didn't pull very well either, who knows. It was cokder yesterday when I tried It. When I drove It down the road it was in the 70's outside, might make a difference? Either way it needs something.

if all you have is a smartphone, try setting the resolution to the lowest setting and upload one photo only.

[jeffaj01]

Try this picture thing again. I set the camera to the lowest quality.
