new to me mud truck

[SmokinRAM114]

well long story short i decided i didnt want to build my 91 any more... so its getting parted out and picked up this pretty clean (for a mud truck) from a friend of mine. its a 78 GMC k 25. right now its a stock 350/350 np203 tcase, 12in lift 3 in body on 44x19.5-15 super swamper boggers. there mounted on a custom 2 piece 15x14 real wheel wheels. i will be adding parts from my old truck to build this so it isnt such a slug.. i have another set of heads that my guy is going to port and polish, a decent cam, new edlbrock intake, carb, fuel system, headers and going to do something not so redneck with the exhaust im not redneck enough for glasspacks:rolf i also have a full set msd electronics to put in it. i have a th400/np 205 thats going to be swapped in probly this next weekend. eventually (after memorial day) i will swap in a dana 60 front but gota grind the brake calipers to fit in the 15in rims.

Does that still have factory diff gears? Or do you just drive everywhere in 4low :goof I would imagine it's a dog with those tires.

there is NOT enough power no matter what gear!:rolf i believe there 4:10s.. will have 5:13s when done

did the previous owner of that truck live in caledonia/racine?

[That_Guy]

was the guy who owned that truck from just out side of oconomowoc..

there is a house on Hwy G just west of husher that always has trucks like this for sale.

[DoubleAron]

Did you have to sleep with your sister before signing the title?

i bought it from my friend in eagle.. he bought it from a guy in big bend. the guy has two indenticle 68? camaro drag cars he used to race at gld. he also has another truck just like this but its light blue with a $8k BBC in it:stare

[Prince Valiant]

Sweet!

Very cool truck...

Are you going to do anything with the short-block? Or are you doing a stop-gap measure until you can get a BBC...or possibly even a diesel in there?

um probly just to get by.. itll probly blow up, i do have a small kit that will probably find its way on there for spring:goof i have a what sould be a healthy 406 sbc that needs assembly, ie everything is sitting in my shop for it.. im lazy and havent takin the block over to kilpatricks to get it cleaned.. i may or may not put that in it. otherwise a bbc would be nice and cheap and make good power with spray :) i can pick one of those up cheap from anywhere too

[lit666]

that truck is awesome, I want something like that to drive to work in.

[WickedSix]

thank gawd you put the tires on it the right direction!!! it drove me batty looking at his pix of it with the tires turned the wrong way!

we need to get another axle back in ty's truck before we test out the new tires :D

:rolf:thumbsup yup! Ill sell u a 350/203 I may have one to sell you ill know in a week

there is NOT enough power no matter what gear!:rolf i believe there 4:10s.. will have 5:13s when done

Well, with 44 inch tires (if I'm reading that correctly), you'd need gears in the 6.40 range to keep it similarly geared (IE, to drive like it has 4.10's...), which, do they even make gears that high for the dana?

With 5.13's, it'd drive like a truck with ~3.23 gears (not counting the effect of rotating mass), assuming it had ~28.5 inch tires standard.

Fwiw, if you did have 4.10's in there now, it'd be like the same 28.5" tire with 2.6x gears...yeah, I can see why it seems like it's lacking power, lol.

[WickedSix]

they make up to 7.17's for the dana 60 the limiting factor for these trucks is the corp 14 bolt in the rear...you can only get up to a 5.38 if you have the 4.10 carrier... 5.13 if you have the 4.56 carrier... but with all high ratios(like the 7.17's) the pinion becomes weaker and more prone to failure. Thats why most trucks with tires over 44" will have some sort of double reduction. Like a rockwell 2.5 ton that uses a r&p to drive a bull gear... or a portal axle that has a reduction box at the wheel drive....or a planetary drive at the wheel end.... or even some guys that keep the relatively strong 4.10 gears in the axles then use a 203/205 doubler to get the additional gear reduction needed. The planetary setup is usually considered the most robust because the axles don't see as high of a load as they would in any of the others. This is why the vast majority of our products at Osh Truk use a wheel end planetary reduction.

[SmokinRAM114]

Someone say 2.5 tons??

[Monstr913]

A guy this weekend tried to sell me a 350-205 that turned out to be a 350-203 luckily pat was there and caught it. No I do not want a 203 chris sorry...but I will take jj's 400-205 lol. And u should 4 link that and sell me the springs...no shamus those are mine lol.

[WickedSix]

wait til the 16x16 rims are here :D

[SmokinRAM114]

parts :)

does this donavan you speak of drive a ram and a bigger kid?

[WickedSix]

that would be donavan.... he also rides a scooter :thumbsup

[-stew-]

Nice rig. 205 is the gear driven case?

[Waver]

Now that is a classic mudder truck. I have always liked those late 70's chevy/gmc/ford trucks with that kind of lift

[Monstr913]

yea 205 is the geared bullet proof t-case...yea thats donavan how do you know him?

[SmokinRAM114]

205 is teh god of t cases like the cummins is god of diesel or a sbf is god of boost hahha

[-stew-]

Are 208's that?

[WickedSix]

Are 208's that?

what's your question?

in order of strength from what i remember off top my head

205-part time 4wd t-case helical gear driven cast iron t-case
203-full time 4wd chain drive cast iron t-case
208-part time 4wd chain driven aluminum 2 piece t-case

interesting thing about the 203 is it has an internal lockable differential that will vary power front to rear when the t-case isn't in a locked position.

[-stew-]

I meant to ask I'd 205's are that bad.

I had a 203 in my 79 powerwagon. I didn't like it. In sloppy snowy conditions when going around a corner sometimes it would send power to the front, sometimes to the rear.

[Monstr913]

Cummins god of diesel come on chris, there easiest to work on maybe, only cuz they constantly break lol. That's for callin the burban junk lol. I am looking at puttin a 6bt with allison 1000 in it, thanks to phill and pat and mean sounding cummins.

[wrath]

Open differential in a NP203, but you can lock it.

NP205's 1.96:1 sucks. Couple that with a TH400 and you might as well just cry.

I just use a NP241 with SYE and 1410 yokes. Weak part of a NP241 is oiling and peeling the case open on a rock. The lowest item on my rig is the frame, and it's at 25". Everything is protected either by the frame or the springs. I have a giant belly pan I run when I go dabble in rocks. I did use a NP241/NP205 doubler for a while but I didn't need it because where I wheeled I needed to be able to spin the tires and bounce through shit more than I needed to crawl at .005mph. And the super short rear driveshaft due to the doubler impeded my joy.

I'll probably end up with a 3 speed case someday. But 6.55*2.72*5.38 is still 96:1. Which is pretty good on 44" rubber. It's enough that idle is less than 1mph and it's nearly impossible to overpower the engine with the brakes.

just thinking of him makes me giggle :D

the only time my junk idles is in park. when the odds of it pushing 600hp on spray 5:38s th400/205 in 4 low is what im going with. i cant stand to listen to a mud truck that is a stock maybe 150hp sbc on 44s and can barely rotate them... and that boring ass rock crawling garbage... my ADD kicks in high with all that dilly dally. if there is power in the truck im using it...all of it.. I bought stock in DART yesterday..:devil few 5gal pails of 110 and 4 bottles lined up for memorial day i hope itll take a 200 hit off the plate :nitrous im sure itll be an expensive weekend :alcoholic

[purpl72olds]

So this thing will be blown up at the first or second mud hole ? To quote someone " nitrous is like a hot chick with an std, you know you want to hit it but its not going to be good in the end" :thumbsup

With 44" Boggers you need 400hp just to drive around on them, especially with a slushbox. You need 550-800hp to use them correctly. A 550hp BBC in a 6,000lb truck with 44" Boggers isn't as much fun as you'd think. A lot of the time you still can't get them to clean. And unless you're doing mud racing, driving around on the bottle is pretty damn boring. In fact, mud racing is pretty damn boring. 30 seconds of fun and 3 hours of cleanup. But then again, I went wheeling every weekend instead of once every couple months.

I gave up on Boggers and went to TSLs because the powertrain cost too much for something that's going to be driving around in water up to the windshield wipers. And I gave up on slushboxes for big tires (and I prefer slushboxes for wheeling) because you need a TH400/C6 to be able to handle all the slipping and those eat power. When you've got 160lbs+ of tire/wheel per corner, most of which is 22" from the axle centerline, the transmission takes a ton of abuse due to trying to manipulate that kind of inertia.

I ended up with a lightly modified TBI350 (dime a dozen, and I've ruined a couple), a SM465 with hydraulic clutch, a NP241 clocked flat with a SYE and 1410 joints, a 79 HP60 with Dedenbear knuckles and Longfield CVs in the front, a 86K30 LP60 with Dedenbear knuckles and Longfield CVs in the back, Eaton E-Lockers, and a hillbilly electric over hydraulic rear steer setup. In the front and back I have the ram stops set so the tires don't rub the 56" springs in the front and the 64" springs in the rear. It's not a ton of power but it does alright because it's relatively light at under 4,000lbs with camping gear.

But anyway, what I'm saying is... don't spend a bunch of money to make a big dumb mud truck. You'll end up selling it for 1/4 the price you have into it because you got bored with it.

:rolf HIT IT AND QUIT IT! i have 3 other 350s to put in.. maybe ill bring a spare:goof:rolf

[subliminal1284]

Sweet looking truck, if youre driving that thing on the street watch out for cops specifically highway patrol they can give you a ticket for the bumpers being too high

[Monstr913]

so you planning on hitting pipeline memorial day chris? how does everyone on here know donavan? i know hes a people whore and all

[WickedSix]

my th400 has the 2.75 low set in it...makes it a little more livable... for just a mud truck i don't think you can beat the 400/205 combo

That's exactly what I want. A toy. I'm not a trail yuppie or mud drag racer that is to boring. I go and find crazy holes and try and get through them pull it out and try it again! If it breaks I'm having fun. I don't care if I can't sell it for what I put in it. I have yet to find a a hobby that'll pay u back for what u put in. This isn't my first mud truck lol
