727 or 904?

I tell you what that transgo stage 3 full manual shift kit it shifted so crisp. You know when you give a buddy a ride and you manually shift the ratchet shifter on the automatic and he instantly looks at you like "that was crisp!" but not banging. You're yeah I know bad *** right?
Of course that's drilling it full of holes like swiss cheese recapping some off, throwing ball bearings out, putting some in, changing a couple Springs, and adjusting some line pressure no big deal...
