I would love to get a T56, but I think the cost would put me over my budget quite a bit. After researching going with a 4L60E, it seems it would be just as expensive due to having to buy the $700 TCI TCU.

Do I just bite the bullet and start savings my pennies for a T56, or is there a way to put a tranny behind a 6.0 that won't cost $1500-2000?

TH350 or TH400

I am using a rebuilt TH400 with a 3500 ACC Stall and hopefully a nice shift kit

I think if you are going carb you are going for simplicity or raw power, so the old schools trannies are used. When you want drivability you keep the EFI and use a late model overdrive. I guess you could always use a 700R4 or a 2004R

200R4 here, dual-fed with billet forward drum (among other nice mods for longevity) and a VIG 3600 stall. Built by "JakeShoe" from Sanger, TX.

i guess you have to fig out if you want overdrive or not-if not, a turbo 350 or 400 is ideal
if overdrive, then whether computer operated or not
the 200R seems to be a better choice over a 700R, then its a choice of a 4l60e or 4l80e, diff in weight and size
i started out with a switch/pitch, old school dual stall turbo 400, but really wanted overdrive, so i got a 4l80e, made it man. shift to save buying a computer, didnt like going racheting thru 3 gears every time i stopped, so i got another valve body, got a deal on a Compushift controller(easy to use/setup) and love it-65 MPH, 2K RPM, sure quites down the Flowmasters, lol
ya, i spent a lot of money, in the long run a 350 or 400 with a good converter would have been wallet friendly-again, use, horsepower, first gear ratio, etc comes into play-im not a trans tech, but i do my own stuff, so i save a ton of bucks that way, offsets the parts price
if i were starting from scratch right now, 200R, no computer, lighter, lots of upgrade parts, someone even advertises it for a 572 B/B engine, so they can be made tough

I am running a 200-4R right now, but if it goes south, I'll probably switch to a manual valve body 4L80. I seldom ever drive my car, so the gear changes won't be a problem for me.

For street purposes, I used a 200r4 from a Buick Grand National. Go check out a GN forum and they usually have used ones for sale pretty cheap.

if you go to turbobuick.com to find a trans. make sure it has br-f code on the yellow plate on the pass. side of the trans. to be a true turbobuick trans(have better valve body)and it's alot more desireable....

I am running a TH350 with 3000 stall Non locking.

Just swapped to a 3500 stall. No new times yet.

You need to purchase adapter/spacer (about 50 bucks) and it your choice to swap flywheels. many use longer flywheel bolts. If you upgrade flywheel go with HUGHES about 120 dollars over TCI (TCI is pricey)

I have the tci plate in mine and it was expensive but I can say it is one HELL of a part. I was very impressed with the quality and it came with a spacer. I didnt use it though since my edge converter was custom built with a changeable pilot. Not dissing the hughes just giving my experience with the tci piece.

What all is involved as far as adapters to mate the 5.3 or 6.0 to a Th-350?
Is it a different converter, different flexplate, or some sort of adaptor?

And, any links to where to get the parts?

I have a possible chance to get a 40,000 mile 5.3L, I know that I will have to either make motor mounts or purchase them, as well as make the harness a standalone, but I am at a loss as to what to do about mating the motor to the turbo 350 trans I have.
Oh, forgot, this would all be going into a 70 camaro.

summit has the adaptor for 45 bucks and all you have to do is oblong the flex plate to fit the conv. but some 6.0's already come with the spacer.

I originally bought a used 6.0 flexplate with the spacer and bolts off of here to use with my TH350 but ended up getting the TCI plate instead. Just felt better about it. I'll sell the flat 6.0 plate now if anyone wants it.
