Hey,

I have a turbo 400 trans. and i want to repalce the converter bolts with some ARP bolts. Now when i look them up it say that he TH350 uses 3/8 bolts and 3/4 long. My converter bolts are 3/8 but I have a TH400. And they say use 7/16 bolts on the converter for a TH400. Do I have a TH350 Converter in my TH400? Can you do That? Is there something I am missing?http://www.nastyz28.com/ubb/confused.gif Please let me now what you guys think.... Thanks

yes a 350 or 400 converter will interchange with another. a 350 converter in a 400 will sneek a higher rpm out of it.a chevy with nut and bolt take longer bolts. shorter bolts with a 400 converter cause they have no nuts and bolts. just bolts to go into converter.

I forgot to tell you that the conveter has threaded holes.

I used the wrong bolts in one with threaded holes once, took me a LONG time to figure out where the leak was coming from...

Good Luck!
