Yet another 904 rebuild thread, what kit?

Ok, so yes, I've seen a bunch of threads on 904 rebuilds. Most are super helpful, but I'm not building a monster engine so I kinda think most of the suggestions in the threads I've read on building bulletproof 904's will be totally overkill for my application. With that in mind, this is for the 904 that's going behind a 318 in my '71 Dart GT.

318 is .025" over, forged flattop JE pistons, RHS X-heads with 1.92/1.60" valves, Lunati 60403 cam- advertised duration 268/276, lift w/ 1.5 rockers .494/.513". Edelbrock air gap intake, holley 670 street avenger, Doug's headers, dual 2.5" exhaust. Static compression calculates at 9.662:1, DCR is 8.265:1. Should be fun, but I think it's a pretty safe bet it won't make any more than 325 hp or so.

The 904 is the original transmission, it shifted fine the few times I drove the car before I tore down the engine. ~84k miles. I haven't torn it apart yet, but there wasn't any giant chunks of friction material in the oil so it shouldn't be completely awful in there. It's going to get a new converter, the cam specs call for a 2400 stall. I have a Transgo TF-2 kit for it and the Mopar Performance +1 qt steel pan with a drain.

I was looking at this kit and adding on a reverse band, seems pretty complete.

Just standard stuff, high energy plates and steels, standard kickdown and reverse bands.

Figuring that I have an engine that will only be a bit over 300hp, I'm thinking all of that should be fine? Don't really think I'm in a performance spot where I'll need red plates, kolene steels, kevlar bands, etc. Just a street car, not a drag racer. I like some spirited driving but nothing too crazy, and I'm sure most of you know by now I'm more of a corners guy anyway. The Dart is numbers matching for all the major parts though and I need an "easy" car to drive so I'm keeping the auto in this one, power steering, factory A/C, that sort of thing. Just want to freshen it up, firm up the shifts, and keep it running smooth for a long time.

So, what say you? That kit, the TF-2 and extra quart pan? Anything else? Or is my thinking off?

Thanks!
