do u need that bar that goes from the trans to the rearend?? its on a 86 iroc-Z

 

Yes you need the torque arm. Without it your rear end will rotate.

 

ok ty alot lol i was just woundering I just pulled out a 700r4 aout and want to put a either a th350 or a 400 r they the same length? cause ijust want to put in and go???

 

I believe the 700 is longer. And if you do swap to a tranny without the provision for a torque arm mount there are kits to fix that. I seen them in Jegs online catalog and would think Summit should have them as well.

 

The t350 is about 4 inches (don't quote me) shorter than the 700 R4. The 400 is a little longer than the 350 but still shorter than the 700. Considering the cost of having a new driveshaft made, buying a remote torque arm mount, refabbing the trans crossmember, and losing overdrive, I feel you're better off and will be happier trying to find another 700 R4.

 

ok thanks guys if u no anybody that has a 700 plz pm me cause i really need one thanks for the info

 

My 89 camaro has a turbo hydromatic 350 transmission form a 76 chevy truck. The 350trans has multiple versions the truck transmission has a longer tailshaft; It's long enough to still use the stock driveshaft w/o a problem. I'm using B&M's 350 adapter kit and polyurethane bushings and trans mount, but those aren't necessary.

 

so i can use a trans from a 70's model truck and everything will bolt up?

 

The adapter kit has the pieces you'll need and you'll be money.
It moves the transmount a few inches and has the stuff for the torque arm.
I'm using the B&M shifter, so I don't know ifthe stock shifter will work exactly.

 

OK but isn't putting in a three speed taking a step backward? Your giving up the low first gear and the overdrive not to mention the lockup converter...

I'm thinking about putting a 700R4 in my '83 Doolie. Better gas milage, killer first gear for pulling the Fuel Dragster
