5 speed behind BB Mopar possible to do without kit?

5 speed behind BB Mopar possible to do without kit? - 01/25/10 06:29 PM

I have a 383 that I would love to be able to put a 5-speed behind..

I would love a Keisler kit, but way out of my price range right now,
but someone pointed me to a link where I see Quicktime sells bellhousings
to mate a 383 to a variety of different transmissions..

I'm thinking the adapter to the Ford TKO 500-600/TR3550/T5 Mustang
Transmission would give me the best chance at finding a decent transmission
at a reasonable price, but then I wonder what to do about pilot bearing,
throwout bearing, and will my stock fork work with whatever throwout bearing is used, etc..

Has anyone ever tried to do a 5 speed swap without buying a complete kit?

Any help would be great!!

over 3000 RPMs at 60 is killing me when I need to take the highway to get anywhere from my house

The engine/tranny mate is a piece of cake. Shifter location and floor pan/torsion bar X-member mods are a different story.

Check the archives. I did it by mating a Mustang spec TKO to a 440 with a redrilled lakewood bell.

Check out the archieves, I've done my own, PM me for more TKO swap info, can get you in the right direction.

I tried searching the archives for 5-speed and nothing of value came up, guess I need to try something else

Anyway, PM sent

Thanks guys

Sure it can be done. Just call up QuickTime and order up the bellhousing for the transmission that you want to use. Then gather up the other parts as needed and make the necessary modifications to the vehicle.

I swapped a Doug Nash 5 speed into my '65 B body car 20 years ago. There weren't any kits avaiable for that swap back then and I made it work. I had to design and fabricate a few parts and I needed some help from an expert for some of the welding but it came out really nice looking when it was finished and it has worked fine every since.

There is enough information out there to source the roller pilot bearing, bell housings and such. I looked at your web page and saw your road runner and see that you have a console. You have quite a few options...One is the mid-shifter option on the Tremec which you will use the b-body non-console pistol grip shifter. Your will have to trim the back pod to fit under the torsion bar cross member. Most don't think of this option. Please note that you will loose the console. If you want to retain the console - you need to look at Keisler or Hurst for the offset shifter positioning. Both of these companies have offset the shifter from the main case and use a connection device to an external shaft. These come up into the factory 4 speed location like your car needs to retain the factory console. If your cut the torsion bar cross member, the options are endless, and you can choose where you want your shifter. Please note that you need to be a capable fabricator. If you are having someone do the installation for you, get a fixed price since trial and error will cost you dearly. You can do this, just take your time and research all the options.

Thank you,
I have no problem cutting, welding, fabricating anything needed as far as cross member, etc.. So no problems there..

Now do you know if the offset shifter on the Hurst and Keisler transmissions are built into the transmissions, or is that something available separately? I want to keep my console and was hoping i could fabricate an offset for the handle to get it in the position needed, think that is something that is possible with the shifter in the stock Ford location, or is there no chance?

Thanks for everyone's help so far!

I have a Tremec kit and noticed the throw out bearing is larger than the original that came with my A833. What I was wondering is, the original clutch fork doesnt seem to sit properly on the throwout bearing??? like the fork is too short?? do they make a longer fork or modify them?? anyone else notice or have any ideas??

The shifters are not built into the transmissions. Both companies modify the rail housing to accept the shifter body which is offset to the left and rear with a bracket. The tail housing is machined for clearance under the torsion bar cross member, the internal shifter rail is replaced to become external, seals are added, linkage components...etc. It all adds cost to the bottom line of the kit. Take it apart, modify it, install new parts, re-assemble, add more new parts, test and repackage for resale. That last sentence is the cost that you will incur yourself.

If you want the proper shifter location, you are going to have to buy your trans from either keisler or classicmopar. Also, a stock mustang 5sp isn't beefy enough to hold up to much hp, so I wouldn't bother with one in the first place.

Also, I assume this is for the car in your signature? If so, keep in mind the issue of the isolated torsion bar crossmember in the 73+ B bodies. I'm not sure but I'm thinking this will likely get in the way of any aftermarket 5-speed transmission. You should send keisler a note and ask if this transmission fits with that crossmember in the way, hopefully they didn't just assume 71-74 was the same. I have been contemplating ditching the isolated torsion bar crossmember, however this requires going to the older 72 and prior shorter style b-body torsion bars and welding hex sockets into the piece of frame that was originally the torsion bar crossmember in these cars in 71-72. If you're not sure what I'm talking about, go look under your car and you will get it.

The transmission is not going to fit a '71-'74 B-body without major tunnel surgery. The torsion bar crossmember is a problem on these cars.

Our bearing is a "modified" A833 bearing. The difference is we modify the inside diameter of it so it fit's the TKO front bearing retainer.

It sounds like you don't have it put together properly.....?

To install a 5-speed on a big block, you need Lakewood bellhousing #15335. Fits A833, NP435, NV4500, TKO600, and a few others I can't remember off the top of my head. The bell is like $439 from Summit.

how much difference between the TKO and say a t45? I am considering the swap behind a mild SB in a Volare. and I would rather have the shifter come up closer to where the stock A/T shifter would be on a floor shift A/T car.
(I want to use a stock console, these cars didnt come with a console and a stick from the factory)
