Purchased a '56 Belair last fall with a 283 and Muncie 4 speed and want to put in an automatic with an overdrive since it has 4.11 gears. Are there going to be any fit issues with the floor or frame?

No, it's done all the time. I have a 700R4 and it's great.

Im a gear guy; I like the spread on the 200-4r better than the 700-r4/4L60e
Neither is better/worse in a practical sense, I just dislike the 1-2 drop on the 700r.
It bears mentioning that you can do what you're looking for with a 4spd. A 2.88 1st ST10 and a set of 3.08s or 3.23s; or an aftermarket 2.98 1st gear M22 gearset in your existing Muncie with the 3.08s/3.23s. Heck with a 283, you could use a 3.11 Saginaw 4spd (you'd need a new shifter though)
Be mindful of WHICH Muncie you have. The 27-spline output Muncie (akin to a TH350 in size) is 0.750" SHORTER than the 32-spline output Muncie (akin to the TH400). get the casting number off the tailhousing and google it, you'll know if its for a 27-spline or 32-spline mainshaft/output shaft. This can help when converting to the overdrive auto.
Good luck!

That was 231 cubic inches, not the same thing as a 5500 pound 4x4.

I agree with both posts above. The 2004r should have been developed more aggressively and the 700r scrapped.

True.
For our application the 200-4R made better sense for three reasons:
1) Stock length, can use stock driveshaft. And it can be dropped from our convertible's X-frame without removing the engine. The 700-R4 is three inches longer than a 'glide or TH-350.
2) The more reasonable 1-2 gear spread.
3) I have a big brother with 20+ years experience building GM automatic overdrives. Both trannies had their teething pains at the outset. That kind of technical expertise is still required to make either trans live under hot rod conditions. The builder needs to know what he is doing, and what components to pitch in the trash. Big Bro was a fan of the 200-4R early on, and assured me that he could put the right shiny stuff inside to make it live.

PS - Off topic, did you ever wonder why GM never put a 400 SBC in a Corvette? Never mind, that's a whole new thread. :confused0006:mmmmmmmmm
I realize the 700-R4 has beefier internals, as well it should, as it was obviously designed for trucks. It has bewildered me why GM didn't produce a version with a closer 1-2 gear spread for Corvettes and Z28's.

There's plenty of those turbo 231" V6s that make enough power to run 10.0 in the 1/4 mile in a 3000 pound car. Some even quicker. They make lots of torque under boost. Don't doubt the strength of a 200-4R, it's not all that different from a 700-R4. You just need to choose the right parts for what you're doing if you build either one.
