Sounds like the passon OD gear set would go a good option and be the closest to fit in your budget and be totally stock-fitting. The .8 OD ratio is a bit of a bummer though.

with a .80 OD, it's not even worth the effort or expense for so little a gain IMHO, besides the fact the OP never alluded to any indication if his car was already 833 equipped?

Here is a video of a T56 magnum in a Charger

Personally I would either get the Passon 4speed OD or a close ratio T56 magnum.
The TKO trans is not worth cutting up your car. It would be my last choice.
Depending how you are geared now a .80 OD might be fine.

Yeah the car is a 1968 Charger factory 4speed 383 car so I really didnt want to alter the shifter hump in it.

Basically it wouldnt bother me to alter the trans crossmember but I didnt want to alter the cars sheetmetal on the trans tunnel or the shifter hump itself.

The Passon .80 ratio OD gearset is really not even worth the trouble as it wouldnt drop the RPM by much at all.

Your choices are limited then, stand in line for the Passon 5 spd, but your limited to a .70 OD

Or just cut the car and be done with it and go either TKO or T56, IMHO the T56 is the way to go...

T56 all the way even if you have to cut the floor, if the Passon blows you probably won’t be even able to get parts for it.

I'm another who says t56 is the way to go... cut it and once you drive it, you'll have no regrets.

I'm sure parts would be available...might take a few years to receive them though?...

Parts might be available, but say in a few years the transmissions start failing ,the place goes out of business, or something happens to the owner.....you might wish you cut the floor.

My post was in jest, seeing how long (years) some are still waiting for a transmission, never mind spare parts..lol!

But I agree with you, cut the car, it's just a machine, modify the piss out of it...

i agree ! if NO modifications are allowed, that means no change over to disc brakes, or alternator bypass upgrades to the electrical system, better wiper blades, etc. and you shouldn't want an o.d. in the first place. it's only sheet metal you are cutting. get the MOST bang for your buck transmission wise. you will only LOVE it that much more, and in the future, you or the next owner can restore it back to stock. then wonder why it is not as much fun to drive, or just sit around [the campfire] and admire it in the "museum".

I was updating my website and found that there are actually 6 different part numbers for the T56 Magnum

-Part# TUET11009 hydraulic clutch 
-Part# TUET11010 mechanical clutch 
2.66 1st 
1.78 2nd 
1.30 3rd 
1.00 4th 
0.80 5th 
0.63 6th 
2.90 Reverse

-Part# TUET11012 hydraulic clutch 
-Part# TUET11011 mechanical clutch 
2.97 1st 
2.10 2nd 
1.46 3rd 
1.00 4th 
0.74 5th 
0.50 6th 
2.90 Reverse

-Part# TUET16885 hydraulic clutch 
-Part# TUET16884 mechanical clutch 
2.97 1st 
2.10 2nd 
1.46 3rd 
1.00 4th 
0.80 5th 
0.63 6th 
2.90 Reverse

The 2.97 1st and 0.74 5th, 0.50 6th will eventually be phased out so get one while you still can!

T56 is huge. I put a viper t56 in my duster in 2010. I like the way it drives and shifts but I have mixed feelings on The 2 overdrives and The .5 od. The close ratio sounds like a better option but I didn't have that choice. I'd like to regear and maybe make the .5 a little more useable. I made a whole new tunnel and modified the crossmember. I just made a separate trans crossover that mounts to the frame connectors.

My buddy has a TKO600 in his 69' Camaro. The 5th gear overdrive is awesome in this car for freeway cruising. He is thinking about pulling it out & installing a Turbo 400 back in it since he doesn't like rowing the gears any longer. I was thinking about buying it off of him when we remove it. I wonder what would be different other than maybe shifter location to make it work in a Mopar B Body. Obviously, his clutch, pressure plate, flywheel & bell housing will not work. I am talking about just the gear box itself.

The GM location is different than the 69-70 or 71-4 B body, but you could ship the tranny to SST and have them mod the case for either B body location, compare costs on used/modified over NEW from SST before you pull the trigger on a purchase

the passon 5 speed might be $5-6k or what ever it is but that is basically all you have to buy and maybe a clutch disc. if you go buy a tremec you need a cross member, drive shaft and yoke, bell housing, clutch linkage might change, a clutch, which all adds up and after all that you have trial and error making sure everything fits and driveline angles are correct. passon 5 speed is a true bolt in deal that can be done on a Saturday morning and out cruising by lunch time and keep your stock floor pans.. just my 2 cents

I agree, but seems like the 5 speed Passon is unavailable, so it boils down to what is the car being used for, and how much money it will cost, and skill level for the install of a TKO. If it is a manual already, and if a Passion 4 speed is good enough, all is needed is an 18 spline clutch, then plug and play. On my 4 speed at 2500, I get around 75 mph with 3:54 gears.

Very true!
The beauty of a Tremec T56 Magnum though is that you can have it right now! Yes, there is surgey involved but it's not rocket science. The conversion can take a few weeks vs. waiting years, so buy one now and be driving by the summer.

Yes,the costs do add up but that is if you purchase at retail prices. There is no way for us small guys compete with Summit, Jeg's, SST, American Powertrain or other Elite Tremec distributors directly so I have to sell my kits at below retail just to be competitve which saves my customers in the long run.
