Yes, the question is surely asked somewhere but frankly I do not have the patience to dig through 20 pages of threads that turned out in the search

I really wonder _how much_ power can a stock th700r4 handle, and how much with a shift improver kit?

TIA, guys.

 

I'd say with a low milage tranny, probaly 400HP but it won't last long, a shift kit will improve line pressure and help, but not by much. Do a good rebuild with a kit like the B&M transkit and install a corvette servo and it will handle 400hp all day long.

 

Ur prolly right boh I love 700-r4's thats all i've ever owned and they've held up to anything i've thrown at em lol

 

It kind of depends on how it's driven and what kind of TC it has in it. Personally I wouldn't trust one past 350hp, stock at least. They can hold up to 600hp if built properly (Pro-Built).

 

Don't get the B&M. Go with transgo and it should last a while if you don't abuse it too much.

 

I've broken two now, with a really mild 400. I don't think they like torque very much. My curent 700R4 has a superior brand (common trans rebuild parts supplier) shift kit and corvette servo, and it seems to be holding up better.

 

i think if u build them right they can hold up to quite a few ponies if built right!! Keyword built right I think if u add a corvette servo and a nice B&M or Tran Go shift kit they old up to at least a good 400 hp (they alwaya have for me) Then if you go putting high performance clutches, a bigger pump, a manual valve body, and a few other things you can do I'm sure they can hold up to a good 600-700 hp
