Hmmm...

[79C10]

I got a crazy idea, well here goes:
I was wondering if the rear end out of my 78 1 ton dually would fit under my
79 c10?

Has anyone else had a pipe dream like this?
If so got pics?
I think it would be f*cking awsome!!

That would make my truck wicked slow,(right? feel free to correct my if i'm wrong assumeing it would b really low geared for the 292 to be able to tun it) anyone know what they ran for gears in the 78 1 tons with the 292 and four speeds?

[Captkaos]

It would fit, but you would have to move the spring mounts to bolt it up. Of course being a dually the wheels would be a little exposed.....

[79C10]

I thought it would fit but I was unsure if my stock tranny would turn it. its a three speed auto I just recently learned of being able to tell the tranny model by the pan I'll have to check it out tommarow.

[79C10]

I'm pretty sure my tranny is the th350, the pan looks like a square with one of the coners cut off. Does anyone have an opinion on wheather the tranny would hold up to the dually rear end? The tranny works real well right now no slippage and fairly decent firm shifts, would I need to put in a shift kit if so which one is a good one? Kinda hate to ruin a good tranny, too bad the four speed out of the one ton won't work.

thanks alot

The axle behind the trans won't effect the transmission, it is what you put in front of it that matters. There is no reason that the 4 speed wouldn't swap over either, you just need all the pieces for it.

I am a little confused on why you are swaping everything over to a 1/2T though, it won't have the same strength as the 1T.

[79C10]

The reson I'm doing this is....
well I guess I don't really have a reson I just thought it would be mean.
The reson I thought the four speed wouldn't fit is because the four speed came out of a two wheel drive and my 1/2 ton is four wheel drive. so your saying it will bolt up to my transfer case? or would I have to change some stuff? if so what?

thanks again captain

[Captkaos]

My confusion, I thought we were only talking a different in rating not 4x4 vs 4x2. There will be stuff you would have to change to get the 4 speed to work, so forgive me on that one.

something else... your front wheels will be 6 lug... rear will be 8(?).... maybe cause some issues there....

10-4 captain
now I'm debating on just fixing the 78 dually. it would need brakes front fenders doors
a clutch a radator new power steering lines other than that the frame is solid the rear end is good and so is the bed and four speed tranny.
I origonaly bought the 1 ton to take the motor out and put in my '79 I got a decent deal so I do't mind putting a few dollars into it if it will turn out decent.
Is the 292 enough motor for the one ton? or even the 1/2 ton? starting to have some serious doubts power wise.
I bought it after it had been sitting for 4-5 years under a tarp the motor runs really strong and is curently out of the truck on the stand getting all new gaskets as I was in the middle of the swap when I started having second thoughts about the one ton being too solid to part out. So I never got a chance to drive it with a load on it is it seriusely lacking in power? what can that lill 292 do? (haul)?

[Captkaos]

292's are pretty STOUT and they were used in 1T's. I will take if you don't want it...

[79C10]

the 292 came out of the one ton. I was looking up the specs online and they said the 292 only had like 5 more ponies and 10 more foot LBS. of torque than the 250. S I was confused because I don't think the 250 in my K10 would begin to move a 1 ton especialy with any kind of a load. What I ment is since the four speed tranny geared that motor down so much how would it work out in my K10 with the th350 and the dually rear end would it be geared low enough to turn the rear end, or would it be geared way to high? Also would my four wheel drive still work alrght?

P.s. captain I got a 250 I will sell you fairly cheap.

[Prerunner1982]

perhaps it may help if we knew your plans for this truck? to actually haul things or to cruize and look mean? do you want 4x4 or 2wd? It really depends on what you want as to what will work... helps to have some kind of direction before you try throwing things together....

[79C10]

mostly cruise and look mean but I would like to keep my four wheel squeal.
might not happen but would like it if it could. I mean of course I would haul things once in a while four wheeler snomachine maybe firewood stuff like that certainly no every day. Sorry about not really having a direction sorta just been writing out loud.
thanks

[Prerunner1982]

to look mean, you could put the 1/2ton parts on the 1ton to get it running.. or you could swap the axle and trans to the 1/2ton.. it would work with the 4wd but may require some adapters..you could run different type wheels but adding a dana 60 front would be the "right" way to do it.. it depends on how far and how much you want to throw at this.. the th350 would work fine.. for what you want...

[1969 GMC]

depending on year, the 292 came in some medium duty trucks like the C/40-60. they have a lot of low end oomph. also, depending on year, the 250 could be had in one tons.

[79C10]

what adapters would I need to be able to get the four speed out of the 1 ton into my half ton and have it bolt up to my transfer case?

thanks

Is the dana 60 the front end the used in the one tons?

[Prerunner1982]

it depends on the trans.. depends if it will bolt up to the motor... probably need adapter to mate it to the tcase... if you know what kind of engine/trans/tcase you are gonna use.. you can find out what adapters you are going to need..

www.advancedadapters.com

yes a Dana 60 is a 1 ton front..

[79C10]

how do I teel what kind of transfer case it has?

thanks alot
