I want to put a T-56 behind a gen IV big block in the 1965 chevelle. Besides the floor pan work, what bellhousing, and what year transmission should I be looking for. Replacing a m-21 already in the car.

How about a 5 speed? http://www.classicchevy5speed.com/
There's no molesting of the original 4-spd hole in the tunnel by going with their shifter that's offset.

1964-67 Chevelle, 1962-74 Chevy II/Nova, & 1964-72 GTO/Lemans:
When using a stock center console, the required solution is to use the McLeod “Slik Stix”, low-profile, offset shifter. You will need to remove the stock Tremec shifter from the TKO and install the McLeod shifter with the main body of the shifter in the forward part of the rear shifter mounting location. Simply unbolt the Tremec shifter and then bolt on the McLeod shifter. The McLeod shifter is a direct bolt-on replacement shifter. Using this shifter requires no modification to your stock console and achieves perfect shift stick positioning. If you are not using a center console, you can use the standard, Tremec shifter.

Copo-
To clarify, when using the Mcleod shifter you will achieve stock shifter positioning in th estock console withoput having to move or modify the console. With that said, the tunnel does still need to be cut and modified for a Chevelle install.

Captainps-
If you must go with the T56, I would look at using the "aftermarket" T56 for the following reasons:
1) It has the best gear ratios for use witha carburated motor - best first gear and better 5th & 6th gears. If you have a fuel injected motor then you could look at th eother T56's.
2) You can easily use your stock mechanical clucth linkage, stock mechanical speedo cable, and stock bellhousing (need an adapater plate on the front of the T56 - this is easy).
3) The shifter position on this T56 is closer to your tock shifter location than the other T56 versions.
Feel free to call if you have further questions.

it`s not the same tranny but my buddy installed a "ZF" 6 spd from a mid to late 80`s vette I think. He used the bellhousing and shifter from the same car. He also used the hyd. clutch set up with the stock brake pedal. It works good except he says the clutch pedal travel is about half of what it was with the muncie meaning it doesn`t go to the floor when he puts the clutch pedal all the way in.

If you don`t already have a tranny, I would look into the tremec set up. It looks like a nice set up. I wish could afford one.

only reason I would get the t56 is because of .5 OD. I still like the TKO better because you can get it rated to 600 ftlbs, plus it has a lower first geart. And, if you are really just picky, you can get a hydraulic clutch set up too. Plus...stock shifter location if that matters.

Just some words of caution, before deciding on what you want, look long and hard before you proceed with the T56 rather than the TKO. The T56 is a super trans, but it's very large compared to other alternatives & when you put the driveline angles where they belong, the stock tunnel size & shape IS an issue on the '64 to '67. You might also want to check into getting all the hardware that you need with the alternatives & add up the totals.
For instance, if you go out & pick up a T56 somewhere reasonable, better get one with the adapter plate as part of the purchase as most of the transmission vendors won't sell the adapter plate (& special pilot bushing since the input shaft comes away from the motor by the thickness of the plate) separately so you can use it on a T56 you've picked up elsewhere.
If you plan to run tall gears (4.11, 4.56, etc.) the double overdrive is sweet (realizing that 1st & 2nd gears might be used just to get across an intersection in town), but if you plan to stay in the "3's" with the gear, you'll be making pretty low RPM's in 6th for your motor torque, unless you plan on cruising 85mph on the interstate.
Check out this calculator for some interesting info on RPM's in each gear, etc.:

Good Luck with whatever you choose.......Odie.

My Viper T56's 2.66 first gear and 4.11 rear cog doesn't equate to a granny low,way more than just across an intersection.
A D&D T56 is rated at 550ft/lbs but can probably handle over 1,000. Same with the Tremec TKO-600.
Nothing wrong with my 6spd but if the TKO-500 or 600 had been available when I bought the D&D,I would've went with a 5spd.

ZF 6spd's were first available in the 1989 Corvette.

if i had the choice to do it again, i'd still stick with my TKO600.. at 70ish im turning 1700rpm... pretty low for a hefty big block. i can't imagine ever needing a .5 o/d unless you have a stock fuel injected engine....

Oh,I don't know,,,1950rpm at 70mph in 6th with 4.11 cogs is kinda nice.
The 22mpg isn't so bad,either. :D
