Idea Trans issues

I just picked up a 71 A833 trans for my 71 RR. I currently have a 3-speed OD trans on my car (year???). I have a 67 440 in the car. Would you go with the 4 or 3-speed? One person told me to stay with the 3 but I dont think so. What do you think??? Thanks.

It depends on what you want to do with the car. If you need something to get you around town and out on the interstate with some decent fuel economy, and you are not going to put much stress on the drivetrain, the OD trans is the way to go. If you want performance and brute strength, and gas mileage and cruising speed are not factored in selection, the A833 is the trans of choice. If you just want better acceleration, your purchase was a good one--the OD tranny has wide-split gear ratios, and it can cause a bog for even the strongest street engines. I don't know what you are after or what kind of axle ratio you have, but for a guy like me who drives his cars on the weekends just to have fun, the A833 is the trans of choice.

More gears = more fun, as well as better performance.
All the new hot cars have 6 speeds...hint hint..

If I wanted fuel economy I wouldn`t have a big block.

I only get 12 mpg with my 440. Economy is not an issue with me. Thanks for the insight though. Oh by the way my gears are 3.23 but soon to be 3.55. Thanks again.

holy crap! 12 mpg, I would kill for that with my 440! (only6 with 3.23s in mine)
Any way to the point, I vote for the 4 spd, if for no other reason-it will give you more options in the future.

before you invest in the 355's, take a good look at your tire choices. You might want to go with a lower profile tire, and need the 323's for correct gearing..

I like the idea of 3.91 or 4.10 with a Keisler 5-speed.

I like the idea of the kiesler also but I dont like the idea of $3500.00 for it. Im just gonna stick with the 4-speed for now. Does anyone know of hand what the gearing in the 4-speed is? It is a 1971 4-speed. Just curious. Oh by the way my tires on the car right now are 295/50R15's on the rear. Cant remember what dia. they are. Will post later. Thanks

I think there were both close ratio and od 4 speeds in 71, the close ratio ending at 1-1

The trans ratios depend on input shaft in 1971. If it has a 23 spline input shaft the ratios are: 1st--2.47 2nd--1.77 3rd--1.34 and 4th--1.00 If the trans has the large 18 spline input shaft the ratios are: 1st--2.44 2nd--1.77 3rd--1.34 and 4th--1.00 They are both close ratios. The 1970 and earlier 18 spline had a 2.65 1st gear and 1.93 2nd and 1.39 3rd gear. The 74-75 23 spline trans had a 3.09 1st, 1.92 2nd, and 1.40 3rd gear (wide ratios)

OK new question, do I need a new bellhousing to put this trans on my car?? I think the input shaft "cover" (front seal) is 5.140" on my old trans and the new 4-speed's is like 4.8" (im not sure of the exacts). If so does anybody know where I can get one?? Thanks

The truck bellhousings are deeper. I paid a lot for the one for my Ramcharger, when swapping from a 318 to a 440. I don't think it would work.

Would that be the same bell that comes on the old 68-69 big dodge truck?
I also have one that is older that has a smaller hole for the collar to fit in.
The 833 collar is to large to fit it.
Also it is a steel bell.
Not cast iorn.
In fact it says steel on it and has the ringimg sound of a steel crank when hit with a wrench.
Have you any info about these peices?

First, I need to tell you that I don't have any first hand knowledge about your stuff.

That being understood, I'd guess that even older truck big block bellhousings would be the same. The "steel" label is puzzling. Maybe it's a cast steel scattershield???

The cast steel units from the 64/65 race hemis,( one of which was on ebay in early Feb), will work with some modifications. I have a 71 runner 383 4speed and wanted the ultimate in blow proof and be able to change the clutch without dropping the bellhousing, so this got the vote.

This info is only for my application, but should give you a good base to work from for others.

First you will have to fabricate a plate to mount the Zbar pivot it the proper place. I made a plate out of steel, cut off the threads to the pivot , drilled a hole in the plate so the pivot base would register against the bellhousing and had it welded in the plate. Then bolted the assembly to the housing with Socket head ,(allen head) cap screws. You will need to take @ .125" off the cap screws to keep it from interfering with the Z bar when shifting and the drivetrain is shifting around. There is NOT enough room for hex head cap screws,( regular bolts) to be used. Flat head may be a possibility, but if they get stuck- you have an issue to get them out.

Second you will need to find an inspection cover from 64/5 or redrill the bottom of the bell housing to fit the later style cover.
I chose the latter.

Third- these bellhousings are made for the SMALL bearing transmissions. For use with a large bearing unit you will have to have it machined out . I talked to keisler about getting mine modified to run his trans- Shafi tryed to sell me on one of his, because these will not fit the newer Hitorq starters. Not that that is a concern for me-,( no headers) and I value my feet more than having to rebuild a starter every 15 yrs or so.

If the opening in the housing is larger than the bearing retainer Just have your machinist cut you a bushing on a lathe and install it in your housing. My Lakewood came with a bushing for this purpose.
