Whats up guys. Thank you for all the help you have given me. Ive got another product I need help with

So a recap. Im building a 1964 plymouth valiant with a 1969 340 block. I have a friend that has this aluminum bell housing for an A833 67 and up. I need help knowing if it will fit my 64 valiant with the 69 340.

According to Brewer's website, that's for '69-'71 A body and '70-'71 E body; fits transmissions with the 4.354 bearing retainer.
They also offer conversion torque shafts and linkage to use the 10.5" bell in '63-'66 A bodies. You *may* have to flatten the pinch weld in the tunnel for bellhousing clearance.
 
Also it fits the A833 four speed AND the A230 three speed.

Thank you for your response.

So I would have to use the 9.5 Bell housing on my 64 not this one ?

Unless your friend has it, and is just not pictured in your original post, you will need to come up with a neutral balance 10.5" (disc diameter) 130 tooth flywheel to go with that bellhousing.
Along with the Brewer's conversion linkage, unless you are capable to fab and modify your existing linkage. (Was your car originally a four speed?)
The later, larger clutch is a worthwhile upgrade- especially with a healthy 340.
 
I used that bell housing in my 64 Barracuda, with no modifications to the firewall. I cluged the linkage and got to work. Just get everything Brewers says you need to make it work, including the HD rebuilt Z-Bar. Also see post #10 above for the right flywheel.

Hey buddy

He doesnt have the Flywheel just what is in the picture. I just wanted to make sure it would work as far as fitment under the floor pan. And no its originally an automatic. My buddy also has the Floor tunnel from Brewers. I plan on buying it all as a package. My 340 will be north of 450 hp so it does need this bigger set up.
 
My understanding is the 10.5 bellhousing fits. It's tight, but it fits. I believe Brewer's sells a modified Z bar for that installation.

Sounds good. Just be aware that the early A body floor humps are different from the later ('67 and up) floor humps- they can be made to work, but they're not a perfect fit.
Good luck with the swap- it's worth it!

I did the same in my old '66 Barracuda back in 1982.

you had a 64 to 66 A833 and the bell housing worked fine ?
 
see the round thing with 4 bolts?

measure that. or get the part number off of it and then match it up here: Brewer's Performance - Mopar A833 4-Speed Transmission and Component Specialists

the bellhousing and that bearing retainer need to match each other in diameter. early a-body cars used a smaller bellhousing and smaller diameter flywheel, so fitting the later, "larger" bellhousing makes things tight-- hence the advice of maybe needing to flatten out the pinch weld in the tunnel to make everything fit.

anyway short version: trans bearing retainer has to match bell, bell has to match flywheel & clutch.

Did you change the bearinf retainer to a 4.345 ? Not sure if mine is that size already
 
66fs said:
Yes, and the trans is in the same position and it uses the same pilot (front bearing retainer), so it does not matter what A-Body 833 trans you use.

Well, I don't know if I'd go that far. That front bearing retain diameter changed over the years and it needs to match the bellhousing. Also, the output went from a ball and trunnion U-joint in the '64-5 models, to the 25 spline slip yoke type in '66-7, to the 29 spline one from '67 big blocks and later. Nothing that can't be overcome, but, it's just more hassle and money if you pick the wrong combo. If the OP is just going to use the car on the street, building a stronger small clutch is also an option. The '70's B-van slant 6 clutch fits the early flywheel, and therefor can use the stock '64-6 cast iron bellhousing and clutch linkage. Another thing you might want to verify is that the crank has been finish machined for a pilot bushing. Otherwise, get the later Magnum bearing instead.

All A-Body bellhousings use the same front bearing retainer, except the O/D. Output should not matter, the OP is merely swapping a 340 and 10.5 bellhousing for the 9.5 bellhousing in his 64 Valiant. The 10 inch clutch from a six would not hold the 340 he is building, unless it was custom built, and then not sure how much I would trust it. Many better options with the 10.5 inch system. Definatly a good idea to check the pilot bushing now.
