Hi everyone! I wanted some info on different trannies before I decide what new engine / tranny combo is going into my 64 98.

Currently my 64 has a valve ticking 394 with a slipping Slim Jim. So even if I decide to put a 307 and TH 200 into my 64 it will probably be an improvement over what is in it now.

I have heard that the TH 400 and 200 4R will bolt right up to a 455 or 403 as long as they have the BOP bellhousing. Is this true? What about a 700 R4? I thought they were only available on Chevy vehicles.

I also heard that the 200 4R would need to be beefed up to handle the torque of a mildly built Olds motor. What is involved with building one of the above trannies. I have rebuilt a TH 350 and my Slim Jim, so I don't have alot of tranny experience. I imagine I can put hi performance clutches and beefy hard parts into a tranny that I tear apart. Or is it better to have someone beef it up for me.

Thanks for the info let me know what you think.
