Not happening on this project as I need that for my 40 Ford and the funds are let's say dry. The 40 will get vintage air before this unit.

I have a heater/AC unit from a kenworth sleeper that I am going to use for my 52 gmc. I may just use it for parts. If that won't work I will go to pick and pull and do some shopping.There aer some small cars that have to have some good parts.

sumtimes there are small multihookup units like the vintage air to be found in wrecked limo's where they regulate the cool air for the rear passengers it shouldnt be to hard to adapt the controlls for those to work with the standard chevy stuff either maibe look for that and use the stock compressor

i dunno im not from the states i figure there some yards that might have one or two i believe theres a website where you can search them online , there more places to find those small units like in the rear of ambulances just look beyond the row of chevies in the yard

I think I have a way to get both of them in there. My biggest concern is getting 4" or 5" exhaust through the frame and missing the trans and drive shaft. I'm guessing it'll have to go on the out side of the frame and cross back over before the RH saddle tank. We'll see if I ever get some more time to waste on it.

You *might* get a 4" pipe between the frame and transfer case, fuggidabout trying to put a fiver through there. Do you have any body lift on it?? One inch would get a four through for sure with good floor clearance, might be enough for a five, not sure though. I wanted to put a one inch in mine a few times, but came up with solutions for the problems in other ways, but I could have set the motor a little higher and got a bit more up-travel, then again, I was only putting a 3.5" through there too.

Ryan, are you needing AC? or just a heater unit?

Well, I have all the inside parts and the outer housing. I'm going to have to locate the other stuff. Like the heat valve, orifice tube or what ever they use, condenser, and I'll have new lines made. I'm unsure of what compressor I'm going to run at this point as well.

Yeah, on my brother's 88 V30 3" was the max on that baby. I knew this RH drive shaft was going to bite me, but I'll deal with it.

[watahyahknow]

there a couple of places that sell oval pipe straight and bended length or width wize and oval to round adapters if you can get a 3 inch pipe in there you could prolly fit that in there too

ive been worrying about that exhaust routing myself. ive also been inactively looking for a ford d60 for the front in hopes that i can miss the issue entirely.

Ryan, make sure you get the 78-79 earlier style. It isn't super wide like the later ones and will bolt right in.

yeah, thats the reason i dont already have it. they are a little more scarce. i keep my eyes peeled though.

you really worried about the 205 sploding? ive seen far more blown up aluminum cased transfers than 205s. in fact ive never actually seen the case damaged. ive seen alot of funny other stuff blow. you are just worried about chasing down spare 29 sp cases? i think with a little time i could make a stiffener plate for the 205 case.

i am also wondering about the 47re pan to driveline clearance. i think it may be a little tight

For the hard to find part of it, but when you make over 500HP the gear to gear wont hold the 1000lb ft of torque very well. NP241DHDs hold well over 1800lb ft and are easier to find.

What he said.

I've broken inputs and outputs with a divorced 205 truck I had. Then I put a 29sp in it and did it again. Then I purchased the pro fab billet parts and broke those. No warranty and no money back from that deal so yeah I'm nervous of 205's with diesel power.

It's a tight fit to get a 4" thru that hole, I tried on mine but only had 1/4" clearance around it and that didn't sit well with me but my engine sits higher than most put them. I ended up jogging outside the frame all the way back (no saddle tank). The hole was already in my inner fender so no big deal. You could loop it over the frame and under the bed to get it back in the center.

Also, the only thing I didn't take a pic of before I came back to cali was my exhaust. My bad.

But it does look good, makes me want to get back to the midwest and drive mine (and paint it as nice as yours looks!)

Be on the look out for that white F-350 on base. That's my little bro. He'll be leaving Thursday for his month long leave though.

I'm thinking right now the out side the frame routing will be the way to go. We'll see what it looks like with a 241DHD in there though. I want to use the 205 because I know it'll bolt right on and so will my tcase shifter. But I know in the back f my mind, the skinny pedal is getting mashed once in a while. That being said, there may be a 40k sled behind it and I don't want to be searching for 205 parts or cases again.

And thatnks on the paint. If I ever get far enough, I'll throw the front clip on and take some pics. My poor running hood.

sorry to hijack. i assume you need to run the early late 80s-early 90s 241? is this the same strength as the dodge 241dhds? i cant find reference to a p-drop dodge 241 case anywhere. also, the GM versions will have a 32 spl. input and the dodge tranny has a 29 or 23 spl input. swapski?

how do you plan to attach it to the dodge tail housing? as far as i know the 6 hole pattern is incompatible as far as clocking goes.

thanks

I plan on using a 241dhd from an auto trans pending it has the speedo set up on the tail shaft. If it doesn't I'll have to use a 241DLD from my brother's truck. I will reclock it where I need it and modify the pick up tube for the oil pump in the tcase. Another advantage to a 241 over the 205, is the 241 has a lower low side.

Today I ordered my billet freeze plugs for the engine and a seat heater for it. More parts for the pile.

I need a steering wheel and shift knob heater.

[ryanroo]

a little something from colorado for your longhorn. i'll need a shipping address. i also promise not to be so slow in shipping it that you have to wait to drive it because of me. more tomorrow on the reason i had to pull it tonight.



ryan

[Dieselwrencher]

No need to ship it in a hurry man! Believe me you wouldn't be holding me or it up. Thanks, PM coming.

[Dieselwrencher]

Making a little progress on the pumpkin. Starting to get turbos on this thing.





I took apart one of our 241DHD auto tcases, and converted it to 5 speed. I then placed it on the transmission to see what it looks like. I think it'll work fine with some work.
