700r4 HP and torque Rating
Anyone know the HP and torque rating of the 700r4 Trans. I may have to have mine rebuilt. I would like to know what the factory specs are before I have it done.
For example: If I decide to put a 350 hp motor in the car will the trany need to be built up.
I have done a few things to the motor( see sig) and need to know were the line is. The car will most likely never see a drag strip. Thanks

if its an untouched stock tranny, id personally get it rebuilt and built well. 700's are weak. And its torque, not hp that will kill it

Thanks for the info.
I agree torgue is the major killer.
The link posted provided the info: its around 325 hp and 400 ft lbs. of torgue.
If im going to drop a bunch of money getting it built up, Im may just go whole hog and get a T-56. I wanted a stick when I got the car, but they just didn't make them,...sigh.
Odds are it will be a long time befor I can do that. So a standard rebuild may be the order of the day and in a year or so get a t-56.
Thanks again.

At the very least get more 3-4 clutches and use a Vette servo. A good shift kit and the trans will hold up for much longer than you think.
I just swapped in the T56 when mine went, but I also had the money at the time.

ok, Thanks
did you do thew swap yourself? If so how much time did it take and did you get the car on a lift?

I did the swap myself. No access to a lift at the time. I used 4 jackstands and a couple of 4x4s to get the car up in the air high enough.
It's tough to say how long it took. I did a lot of other things while I was doing the swap. I built a complete new dash out fo steel and aluminum for one, and that took a lot of time. I also completely rebuilt my trans before I swapped it in, plus I added a steel 3-4 fork.
If I just had to do the swap I'd say a full weekend wouldn't be a problem if you have everything on hand, all the tools you need, adn a friend to help you wrestle with the trans.
