I think the 5 speed will be a significantly easier swap. The T-56 is going to require you to cut and make a custom trans cross member. It is significantly larger transmission. All that said - I'd go with a T-56... but i'm biased

I went with a T56 in my car too (non-Mopar though ) If you have to remake stuff anyways, I don't see why not have the advantage of the extra gear And I just set the engine and trans angle the same it was as the donor car basically...

with EFI, I say go for it. but with a carb, I'd say try to keep your cruise RPM above 2000 rpm, or run a "stock" cam with no lope, that is all done power wise, by 5000.
my big block was running a cam that was 1800-6000 rpm power band. I had a TKO with the .64 OD and 3.23 gears with 28" tires.
5th gear was useless unless I was going 70mph or faster, at 65 my RPMs were down at 1700-1800, and the engine was lugging and surging. I tolerated it for a year or so because I knew the whole time that I was planning on 4.56 gears in the rear. and once I did, everything was great! tons of low end, and yet I could still cruise the highway at 2400 rpm, smooth as glass at 70mph.
the TKO will be smaller, and with the .64 OD you don't really need 6 gears. in a 1/4 mile run, you probably will NOT be shifting beyond 4th gear. I feel like you really only need 4 gears for pulling, then a 5th gear OD for cruising.
with that TKO I was running, the 4.56s, 28" tires, the top of 4th gear for me was up around 110-115 mph. I don't need more gears beyond that!

I went with the T-56 for my 56 Dodge 408 Stroker. I will run it with the EZ-EFI setup. I did a lot of research and unless you can rebuild and upgrade a GM T-56 the brand new in the box Magnum T-56 for about $2800 or so is the way to go. (a GM core will be 800-1200, and you are looking at nnother 800+ for a good rebuild and upgrade). Yes they are BIG but the effort will be worth it. I also have a fairly comprehensive parts list with prices for what it will take to install one to a small block. I learned that I could buy a complete kit for only a few hundred more than I could cobble it together myself.

The driveshaft will have to be custom made. Mine came as part of the kit that included the bell, clutch, flywheel, hyd bearing, bolts, etc.
I believe the yoke is a std GM size.

As far as the floor, you can make a LOT of room with an acetylene torch and an 8 lb hammer. I cleared about 2" at the bellhousing just by heating and stretching the metal.
