Ok guys. I thought I learned my lesson on how to only buy once, but yesterday my 2004R failed in a very loud but not so spectacular way.
So rather than fool with it, I am going with a 4L80. Hindsight is 20-20, and I should have done this to begin with...

US Shift Kit Builder Results

Now that you've completed the wizard, the combination you should order is shown in the chart below.

I have barely started looking, but this kit above seems good to me.

Does anybody have one that might work better, or be more of a value?

I like my bench seat, and column shifter so being able to dial in my shift points is one thing that I really need. There will be nothing too fancy about the trans. No transbrake, or manual shifting needed. Just needs to wring out to 7200ish RPM and not go BOOM like the 2004R did.
I have a Freakshow Converter being built, and my 4l80 core will be here tomorrow. The trans builder says the 4L80 is comfortable with 1000 HP, and I am nowhere near that.

Thanks. Just an update for this thread, I'm seriously leaning on going with the Edelbrock controller. I already have the Proflo 4 injection on this car, and they are supposed to play nice together. Just two wires to hook up to the Proflo pigtail, and the transmission controller can read inputs for RPM and throttle position.
I already have my freak Show converter, and my tail shaft has been sent in for the speedometer gear install. My transmission guy has the core, and he is working on it right now. I also have received my new crossmember already too.
The car went 11.7's at the track. This is with a 342 gear which crossed the finish line at about 4,800 RPM. Also the car was short shifting at around 5500 rpm. So I never really was up on the cam at all. I was too scared to manual shift at the track, but started manual shifting it the next day when I got home and I could tell the difference in the way it ran. But shortly after that the 200 4r gave up the ghost. Something went boom! And now I have 14 neutrals. But the park pawl still works!
I will be installing some 410 rear gears along with stronger axles in the very near future. And I'm sure this car will be in the tens very easy!
