Trans choice questions.

Ok, I am looking to upgrade my transmissions. I have a GT/DA Camaro with the 402/300 engine, car weighs 3210. I have two TH400 with alum drums, etc. These easily last a 100 runs without much more than a fluid/filter change. Would like to upgrade and hopefully pick up some. Protrans out of my league currently. Here are some options:

Redo TH400s with some lightening (I have access to a machine shop to gundrill, etc) alum reaction carrier (help?). Probably not much faster but still bullet proof.

Kilgore TH400. Should be faster (any idea how much?) and I hear they have alot of the issues fixed. Will they last?

Build TH350 with alum drums, lightening. Any idea how much faster? Will it hold up?

Rossler or Coan TH350, can maybe afford one to start with. How much faster do you think it would be?

As a side note, I have a GM 904 core and could get another. Would they be strong enough behind a low hp big block with alum drums, etc? How much faster?

Have some concerns about these smaller trans behind a big block. You can PM me if you don't want to reply here. Thanks for any help you can give me!
