A833 four speed behind a sbc?

I have recently came across a dodge four speed for a b body big block and i am curious on how to get it to bolt up to my 383 chevy. Does it have a pattern that i can redrill the original housing or is there an adapter available?

 

I think GM used Mopar o/d trans in the 80s with both a GM and Mopar bolt patterns so look at mid 80s trucks and some astro vans.

 

there are adapters that were made but i have only seen them for a bbc. to do that the imput shaht had to be cut shorter. the 833 is for sure stronger than a muncie thats why the early pro stock drivers used them along with the dana 60. if the 833 is a 18 spline it would be a shame to ruin it. you can get enough money out of the 833 to buy a muncie if it would work for you. and it would save the hassle of a adapter.

 

I agree the muncie would lessen the hassle but i was also looking at the bullet proof aspect of it.

 

How much longer would this be than a th350 and wat would be the pros and cons of this swap?

You'll need to read this .

Should be a bolt in deal with the right parts - all oem parts too

 

Mopar guys spend big bucks for certain items and your 4 speed might be one of them. I would do some research on the trans and try to get a value on it. It might be worth enough you could buy a brand new M22 that would take all your small block could throw at it. I have run a Muncie m20 behind a stout 454 for a few years and havent had any trouble with it. I wouldnt want to do the mods to make the mopar trans fit.

 

Hell Ya!! I'd run it!! I have broken my share of muncies and T-10s in my OT chevelle. I finally ran a liberty pro shifted Ford Top loader behind my small block 406. I am not sure about the Mopar trans, I know they have a long input, but to run the top loader in my chevelle I used a lakwood belhousing, drilled my own holes for the ford pattern and welded nuts to the back side. I turned the front bearing retainer down to the chevy size to fit in the large hole in the belhousing, and turned the shank of the retainer that the throw out bearing slides on to the chevy size and also shortend it. I did all that on a brake lathe at work, it was very simple to do. The input on the top loader is just a little shorter than a muncie and the pilot is larger, so i had a friend bore a standard brass bushing out in the center and then I pounded it in the rear of the crank, but not flush like normal, i left a little sticking out. I am sure you could get creative and do something simmilar to what i did with the top loader!!!!

 

Now that's hot rodding ^ no crybaby stuff, just make it fit with random tooling

 

It has been told that Sox & Martin ran a top loader Ford transmission(secretly) because it was stronger than the Chrysler. If the Chrysler 4 speed has a longer input shaft it, should be easy to make a spacer/adapter for the Chevy motor.

I also know,(This will raise ALOT of hell), But if you are gonna do ANY sort of drag racing with good tires or slicks, you WILL bust those muncies. Not only did I, but I have fixed plenty of them for freinds of mine. Part of the problem with muncies or T-10s with aluminum cases, is that over the years the case streches and the gears start to ride differently, and that's when things go BOOM. So yes, it would be alot easier to sell the 833 and buy a muncie, both go for big money. But if you wanna have some fun and beat that thing, I mean really beat that thing! I would go with the 833.

 

One of these would simplify things.

 

i've got one, reasonable.

 

I don't know what an 883 box is, but if its a hemi box we ran one in our pro gas car in the 80's. It was pro shifted by Trans-End in Jersey and it required an adapter that was about 1" thick. It worked great and never blew in years. If the 883 is the same box there is no need to cut input shaft, get adapter and use appropriate clutch disk.

Ill take it Scotty t

 

I have saved mine for a pattern. As you can see, it has a couple of cracks.

 

I'm running an A833 in my '36 Ford. Mine is out of a '81-'87 Chevy light pick-up. Chevy used these and 3rd gear is 1:1 and 4th gear is a .73 over drive. There's (2) different A833's as used by Chevy - one has the Mopar bolt pattern and requires an aluminum bellhousing (cast #15530202) which has both the Chevy & Mopar transmission bolt patterns. If you can find one of those bellhousing, it'll mount right up to a SBC and accept the Mopar transmission.

The other A833 as used by GM has the chevy transmission bolt pattern and uses a conventional Chevy bellhousing. The A833 has a 5-1/8" (truck) counterbore.

The A833 used in Mopars were a true 4-speed and are a tough transmission, from what I've read.

 

you gotta come and get it!

 

I was elated with that 'tidbit' of information. Imagine...a factory adaptor! (to match such strange bedfellows as Chev & MoPar)

An additional piece of info:

I had my roadster all set up for my 455 Olds/'37 LaSalle box...I discovered a Buick/Olds/Pontiac ('BOP') aluminum bellhousing that was drilled for Chev (wide pattern) AND Ford (small pattern; but toploader Ford trannies have both small and large footprints drilled.
I happened to have a Lasalle trans-to-Ford bell plate adaptor, so they were a match.
Oh, that BOP adaptor: It has starter mountings on BOTH SIDES of the bell housing, left AND right. (Jeep application)

 

A lot of scattershields had both the GM and Mopar tranny bolt pattern on them.

I know I had a Lakewood BOP one that had the GM and Mopar pattern on it.

I put the Ford bolt pattern onto a Chevy scattershield so I could use one of those fucked up Camaro/Firebird World Class T5s with the Ford pattern I had laying around in my '56 Chevy....

 

I did this conversion years ago in my 260Z. Used a Trans-dapt adapter and Lakewood scattershield. There was an issue with input shaft depth that I never solved. I sold the car and the new owner switched to a Glide.

 

I ran a Chrysler 4 spd in my BBC powered B/MP Camaro back in 1970. No adapters/bellhousings available back then. I took a 1" aluminum plate to make up the difference in the length of the muncie/mopar input shafts (also shortened the chrysler input bearing snout to Chevy specs) . I drilled and countersunk the Chevy bolt pattern to bolt the plate to the Chevy Lakewood bell housing, bored the plate to the Chrysler T.O. bearing retainer diameter and drilled and tapped the plate to bolt the transmission to the plate.. I cut the snout off a Chevy bearing retainer,turned down the Chrysler bearing retainer to the ID of the Chevy unit and locktited the two together so I could use a Chevy T.O. bearing and turned the ID of a Chevy crank input bushing to the Chrysler diameter. Then used a Chrysler clutch dis/ Chevy pressure plate to complete the adaption. The whole deal worked perfectly and the lower first gear of the Chrysler trans compared to the close ratio muncie it replaced put the rear bumper of the Camaro on the asphalt with a giant wheelie the first time we tried it out and required a whole new starting line technique.

I could use one of those adapters if anyone has one. I'm putting an a 833 in my 55 behind a 331 sbc

 

Swap the Chev 383 for a Dodge 383 and have a good motor to go with the good transmission and no hassles making it fit.

 

...and yet, no one has asked Tom to make one off of his sample...kinda weird.

I have 2 833s for sale and a 3speed with overdrive.One of the 4 speeds is modified for use behind the chevy as it has the input shaft shortened and a very nice adapter also has been slickshifted and has not been run since modified.The other trans has a twisted input shaft as it was behind an alchohol burning tractor pull tractor but is otherwise in good shape.Both trannies have the ball and trunnion output shaft and the 3 speed is a regular slip yoke.All three are for sale.

 

What happens with those aluminum case 833s is over time the counter-gear shaft eggs out the aluminum case in which it rides. When there is enough wear it eventually lets go. There's an article in an old mopar muscle magazine about putting steel bushings in the aluminum OD cases to make them reliable transmissions.

 

I would run it and yes mopar made one for 80s chevy trucks, so finding one of those wouldnt be bad either....

 

I know this is a old post, but does anybody have another adapter laying around? Im trying to also put a chrysler trans behind a bbc. If not, does anybody know of a company that makes something to do this? I cant find anybody that makes parts to do this anymore.

 

I had forgotten about the Chevy version of the A-833, and now just learning there were actually two different styles, but, everything is a compromise.

I used the O.D. version if the A-833 in a two different Mopar vehicles I owned, and while the overdriven 4th gear is nice for highway driving (I think I knocked down 18-19 mpg in a shorty van with a 360), the gear spread is not great IMHO for, well, all other driving situations. Essentially, 3rd gear in the O.D. version is 4th gear in the non-O.D. version (1:1, the 3/4 lever on the side of the trans is flipped 180*), so you are asking the O.D. version's 2nd gear to span both the 2nd and 3rd gear ratios compared to a non-O.D. A-833....not ideal.

There's one of the Muncie-bolt pattern Chevy A-833s on fb marketplace near me currently, so I figured I'd add a pic of it for future reference:






The "other" Chevy version is pictured in the classicjunkyard.com link above (still valid), and should stand out like a sore thumb.
