904 rebuild/advice :)

Hello everyone. I have decided to rebuild the 904 tranny out of my 68 cuda.

I have a mild 318 with about 350 HP, but I would like the tranny to be built to support about 450 HP for future engine upgrades.

So, what is your guy's recommendations on parts I should use? What clutch packs, bands, shift kits? any other mods? I would like to keep the forward shift pattern. I already have a turbo action floor shift unit:

This is for a hot street car, with an 8.75 rear, 3:55 sure grip. Can budget about 5-600 for parts...

I already have that HP book on how to rebuild the 727. So I will use that as a guide as well...any and all help is appreciated
