So yep, 84 Camaro Z, got the 700r4, 1st to 2nd is ok at WOT at low rpms, worse as rpms rise, 2nd to 3rd sucks (flares bad, especially at high rpms), 3rd to 4th is slow to drop.
Most everyone i talk to says the 700r4 wont hold any power unless you dump $$$ to beef them up, which I dont really have. I'm lookin to spend $700 max, including installation. My moms friend gave me a th350 last night for a couple beers, because its been in his garage for 15 years, and he isnt planning on using it. He had it rebuilt by a good tranny guy --- 15 years ago, so, seals and such are prolly rotted by now wouldnt you think?

I was just planning on getting it rebuilt, for $400, with a heavy duty sprag, good clutchs, etc, and a street/strip shift kit. Thats the lowest so far, im going to do some more checking.

He said he thinks its the short tail, so main questions are:
*What driveshaft? Custom, or is thier one that will fit?
*B&M torque arm kit right? Whats it got, part #? Anything I have to do really?
*Run a vacuum line back ? My manifold should have a port shouldnt it? It's still the stock 305.
*What type of stall should I get? planning on 350-400 hp out of a 350, but right now its the 305 (low output).
*What sprag do I want? 36mm? 29mm? And the red clutch bands right?

And lastely, should I really go to a th350? Its a street car, but their so expensive and no1 around here really knows what they're doing w/ 700r4's, and im not dishing out $1500 for a bowtie.

Budget huh? OK here goes.

Get a Crossmember AND driveshaft from an 82 V8 car. Driveshaft is PERFECT length. Crossmember works fine too. Then you'll need the Hurst or B&M Torque arm kit. I HATED the B&M kit. I used the Hurst kit on a friends car, and I liked it better.

Then you'll need to figure out how to make the speedo sensor work.

As for stall, I say 3000 is minimum. I had a 2500 stall and it was pretty lousy. We have a 3000 stall in a friends AOD Mustang and it really woke it up.

Id also highly suggest a GOOD tranny cooler. well worth it, will save the tranny under hard abuse.

If you cant snag an 82-83 1/2 Driveshaft or crossmember, prepare to fab a crossmember and get a custom driveshaft.

Question...is the tailshaft the long or short tailshaft? I had the short one when I did mine few years back.

A TH350 in stock form should be able to take that HP unless your really really running the crap outta it... A slight buildup and i wouldnt even think twice of it blowing up behind a sub 400hp motor.

I have beat the ever living crap out of my bone stock TH350C (apparently slightly stronger than a regular TH350) and it hasnt gave me one bit of problems and my new motor has a fair bit of grunt.


As for a stall, thats going to depend on your cam choice. You want to pick a stall speed that is just a few hundred below where your motor is making peak torque. Any lower and it will be a dog off the line and any higher and you blow right by your torque curve and the car doesnt pull very well.


Heres a couple things i can think of you needing:

Torque arm relocation bracket
Custom driveshaft, though you might get lucky and find a JY shaft to fit
Either get a new crossmember or relocate the stocker
A pile of speedo gears from the JY to get the speedo right (or order up the exact ones)

To the one guy, its a short tail i think.

Thanks alot for the info ! Thiers a million camaros sittin around here, I know the owners of a few yards, I should be able to grab a DS and a kmember alright. Anyone know how the long the driveshaft has to be? So that i can measure and get it right.

Also, links to the kits? Speedo gears? And what sort of build up? Just a bit better sprag and some good clutch bands?

And as for the stall, I guess i'll just have to go stock and replace it when I get my engine, cuz im not even close to sure what i'm going to go with. My moms friend has a couple 327's, another friend has 350's, depends what I can get easy, and cheap. Guess I'll have to get the stall when I get my engine dyno'd

If it is indeed a short tail your in for some fun...

The long tail TH350 will bolt up to the original mounts and use the original driveshaft as it is only about 2" shorter at the mount and less than 1/2" shorter overall.

If you do have a short tailshaft i would reccoment you pull a long tailshaft to throw on it from the JY and save alot of hassle.


Hmmm, now im having a hard time finding the torque arm relocation brackets... I thought for sure B&M made the kit...

Heres another not so cheap solution, jegs sells their torque arm with the bracket that relocates the mount....

is it pretty easy to do it? When i have it rebuilt will it be pretty easy for them to swap the tails?

84z28350

Pretty simple to swap tailshafts.

And while they have it apart make sure the speedo gears are correct for the rear end your running. You dont really want to tear into it twice if you dont have to!

Burntz

Yea that definately sounds like a good idea, so i dont have to find another driveshaft and stuff lol

TBI92Camaro

Seriously, its not hard with a short tailshaft.

82-83 TH200C driveshaft and tranny crossmember (NOT k-bemember for the motor!)

I didnt mess with the speedo, I ended up with an Autometer piece anyways.

Burntz

yea but if the shop could swap tail's pretty easy, then i wouldnt have to go find that stuff at a yard

Burntz

HELP!!!

I'm doin the swap now, having my guy do it. I had him change it to a 9 inch because i could re-use my tailshaft, but now the brackets wont work? **** LOL

What do I have to do to make the 9 inch tailshaft work?!

Burntz

anyone thier? help

I used the stock 700 mount, crossmember, driveshaft....had to use the 9 inch tail th 350, mount was off by about 1 inch, nothing too hard to work with.

the b&m kit sucked, never used the hurst kit. but then again working on custom cars ins a lot more work than on factory cars. the b&m kit i had to modify a little to get it to bolt right in. oh and dont forget the detent cable and the proper bracket cause the stock one is not working for my swap. trust me if you forget it you will dump at least 2quarts a day of trans fluid a day out. two cases in as many weeks cause my teacher told me that my trans didnt need a detent cable and i didnt research

Burntz

well my transmission guy said he's ordering in a block spacer for my 9 inch 350 (which is 100 bucks), which has a bracket or something welded on for the torque arm? im confused about it all but he's sayin it'll work, otherwise he'll be redoing it lol

any1 know what he was talkin about?
