Beefing Up 904

Topless69 said
I know this has been discussed often here on FABO, but I also know tech, means and methods and parts selection are updated regularly, so here goes…
I’m replacing my original 318 with a 340, and while it’s out, I’m taking my stock 904 to a shop for rebuild/strength updates.
Any suggestions, advice and help you guys could offer would be greatly appreciated, since I know next to nothing about automatics and they’ve always been something of a black art to me.
Whatever brands, parts, advantages, disadvantages and pitfalls recommended will be studied, researched, pored over and implemented with great care, as I only want to do this once.

Thanks in advance to all the FABO tranny gurus and everyone else on this great forum for all the help and advice in this project!

After doing the same research while my old 273 was out and I was waiting for my BPE 408 to arrive, I had a parts list $1800 deep and sill hadn't picked out a converter or found someone to do the buildup confidently.
Then I went to the TCI website and saw that for around $2k I could get a new Streetfighter 904 good for 400 HP.

When it came I put it all together and now with about 2500 miles and quite a few hard acceleration events; I am very happy with my choice.
Something to think about...
