Well after a few discussions my motor builder is saying if i want overdrive, better go 200-4R cause its a better tranny.

I'm still skittish on the idea, but i've found a 200 for 50 bucks, that needs to be rebuilt. it was fine in the car, just been sitting, but its a good candidate for what i need.

I'm hoping this is a good decision to go for, as i really dont want to do anymore tranny work than i have to down the road.


As the 200-4R is 28 1/4" long and the 700 is 30" long, i'm assuming im going to need another drive shaft, so what kind of donor vehicles do i need to be after, and can anything from my 700 be used?

What do i need to get to make it fit with the crossmember, and torque arm arangements.

Thanks,
-Scott

 

I've spent the last little bit doing some research, and found that the 200 is weaker than the 700 but lighter..

I want to stay 700, but he's saying not to. I'll ask him today if i get the chance, and we'll see. I still think 700 is what i need...

 

You could use either trans and have it built to work with your engine and rear gear . If you go with the 200-4R you will need one with the Chevy pattern and you should get a tranny crossmember for a 400 swap and that relocates the torque arm to the crossmember . You can have your shaft lengthened or get one made because the trans side is 27 spline on both . And the 200-4R came in alot of cars . I will try and scan the entire article I have from High Performance Pontiacs Pontiac Tech Special where they put one in a '67 GTO .

 

Thanks man. I'll look into the 400 swap member. and i'll talk to the guy that has the 200 in about an hour after school.

 

I am still trying to get the scans uploaded for you to see them . When I get them I will post back .

 

Alright thanks. the relocation member looks to be about 230. maybe i can catch someone parting one out..

 

PM me your email addresse and I will send you the scans .

 

Physicaly the 200 is much stronger than the 700, but in stock form it's a very soft shifting unit that'll smoke the clutches under a lot of TQ/HP.

The stock pan is also shallow and will starve the trans under cornering oe accel.

A built 200 can easily handle 1000 HP and usualy returns better times at the strip due to it's better ratio spread.

A 700 will typicaly come with a rating of no more than 500 from most builders , some claim 600 or 700 but thath really iffy. A new gear set just came out for the 700/60E that fixes the ratio issue, it costs several grand though just for the part! It's a popular trans though so companies are introducing parts all the time to make them stronger.

 

make sure you are getting a 2004R not a 200C! The 200C is weak, the 2004R is what they use in the Grand Nationals, etc. It can be built to withstand 1000HP.

Also, I think I read from my research of the 2004R in the third gen that a driveshaft from an earlier (82?) Camaro/Firebird with the 200C will fit. Again, going on my memory on that so don't quote me on it. There are also aftermarket driveshafts available from Spohn.

Found the thread about the driveshaft. 200C driveshaft from an 82 TA should be the length you need if you don't want to go aftermarket.
