For the manual shift guys.

Wondered what you guys are running for a tranny and rear end??? On my '57 I'm trying to stay somewhat era correct (mid to late 60's) on most things...but as for transmission I have a very nice shifting Doug Nash 5 speed that I've used and abused in numerous projects over the years... I'll probably run it unless I can score a 4 speed Jericho or something. Whatever I run, it'll have to be a full out competition unit (as in no clutch shifts). Kind of a PITA on the street, but I've ran them before on the street... Rear will definitely have to be a 9" Ford, got a number of center sections that I've accumulated over the years so I already have a fairly good selection on gears....

Just curious what everyone is running in theirs, street, race, or a combination....???

Butcher, is that your car in the avatar? If so is that using the TKO 600? Do you race it or is it primarily street? Just wondering what kind of abuse it might see/handle. Thanks. Mark L

Mark yes thats my car in avatar, no it doesnt have a tko 600, 600 is in my street 55. in the picture it had a 400 with trans brake. it now has a glide and different engine. I do have a doug nash 5 speed with straight cut gears supposed to handle 800 h.p. that i am going to put in it later.

We run a Jerico in the race truck with a Ford 9" and 4.86 gears. I love it. I know the truck probably isn't as consistent as it would be with a glide...but what's the fun in that?!
I've had several transmissions in the '56. I started with a Muncie M20 and that worked pretty well. I put a TKO600 in it but didn't have much luck grabbing gears. When I ordered the transmission I told them what I was going to do with it and no one told me about the "Do Not shift this transmission at over 6500 rpm" label that was going to be on it when I took it out of the box. It seems great at 5000 - 5500 rpm but at 6800 I could not consistently hit every shift. I put it in my '64 pick up street driver and it works great there.
I'm a stick shift guy...there is just something about grabbing gears!!

I'm running a TH350 behind my 327, with a narrowed 10 bolt Chev y. I'd have gone 9" Ford, but a buddy had this 10 bolt already and it was a perfect fit, so I figured I'd run it until it breaks. 3.73 gears. (if it does!)

In my 51 Austin I have a Doug nash 4+1 and 9" with 3.25 gears


That's the street version with the synchros so you can downshift, right??? I've got the comp version of the Nash, been looking at the Richmond 5 speed to put in it for the street and save the Nash for race day.

No its a comp version I actually have 2 of them, I talked to liberty Gear about face plating one of them,After face plating I still won't have that much money in to the 2 of them.
I can't wait to drive the Austin and see how the trans works before I decide on face plating or not.

Ford Motorsport Z spec T-5 ( I run it on the interstate) with G-Force cluster gear suport and 3/4 shift fork. 9" N case 4.56 spool w 31 spline Moser axles, shortened reinforced 57? housing. It's held up so far to 4,000 RPM launch with 3,000 lbs of car and driver and 425 Windsor stroker for power.

Not period correct but just had a Tremec T56 built with 9310 internals from GForce. The gears were dog cut and Liberty transmission face plated them. RPM transmissions managed the project and assembled the transmission modifying the case extensively in the process. We are going to use it as a backup for our FTI built TH400. When we do run this we will use a Monster triple disc clutch.

Well, speaking of being long, I finally made my trans decision (for now, lol). I remembered that GM bought Heavy Duty Three speed toploader transmissions from Ford back in the day ('64-71) because the big blocks for the non chevy groups were torque motors and were breaking the little GM three speeds. GM did some testing of the Ford Dearborn three speeds and from all reports, they could not break it. Remembering that I would like a manual trans for the fun of it, needing a strong trans that can handle a lot of power, and one with a good gear spread, I got on the Ford/Dearborn three speed hunt. Most all GM guys that finding these cars with the three speed immediatley went to a four speed. Most of these three speeds were sold off or usually thrown away. A few kept them (thank God) and they have been collecting dust on a shelf somewhere. A good friend of mine found one for me and it is resting piecefully in my garage.
Now the reasoning behind the unusual item. First is was very affordable. Second they are very strong. Third, and from a performance standpoint, it is the perfect manual trans for the job.
Being turbocharged you want to work the engine to make exhaust pressure. The wider gear spread allows the turbo to make power (actually torque) for along period before everything gets interupted with a shift. The wide gear spead (2.44 first-1.61 second,1-1 third) will give me a nice pull from gear to gear. And most importantly, it's one less shift for me to miss, LOL. I bought a used Centerforce disc and pressure plate that will get me all together and on the road for initial start up and some road use. It will not be the ultimate clutch choice but that can happen once everything else is in line. I got a blow proof bellhousing, so all I need is to get all the hydrauic throwout bearing and accompanying parts to make that work. I bought a Mr. Gasket V-gate in line shifter and then a friend offered a Hurst V-Gate at a very low price. They are for 4 speeds but I can make them work well for the 3 speed. Then when I settled on the best one I'll sell the other. Mark L

Here is what my cars have:

66 Falcon- T-5 WC and 9" with 3.50 gears trac loc
69 Mustang-4spd toploader and 9"with 3.25 open diff
70 Charger-A833 4spd and dana 60 with 3.54 sure grip

As you can see, I love manuals. My friend has a 70 Mach 1 351c 2v that came with a 3spd from the factory. He eventually swapped it out for a 4spd and saw no drag strip improvement. He is now running a T5 5spd, but I can't remeber if he ran it at the strip.

I love the toploader. It can be shifted hard, and takes as much power as you can throw at it. I also love the whine from the gears.

I'll be running a mopar 4 speed. Its what i call a street version of the crash box. I performed the mod myself. I ground out every other tooth on the slider but left the dog ring on the gears alone and left the syncros in place. It will shift like a crash box but with be able to down shift like a normal trans, and the mopar trans are tough as nails.
