I have a friend with a muncie M20 tranny that I am going to buy. What I am looking for are pics of how the shifter comes through the floor. Is it off to the side of the hump? Anybody out there still running a 4 speed ?
Let me know how you like it & what you don't like about it
Thanks
Tommy

It's a great transmission, I run one in my '63 Corvette. It has a nice low 1st gear (2.52) and it can handle a modest amount of HP.

The HURST tri-five shifter is universal for ALL the 4-speeds - T-10, Muncie and Saginaw. What IS different is the "Installation Kit" with the shift rods and mounting hardware, sold seperately. I'd say that my shifter sits pretty close to center on the hump in my '57, with a Saginaw-3.11.

The Hurst is a PITA to install, as the stick doesn't unbolt from the shifter body. The stick comes forward 2-1/2 - 3" to clear the bench seat, then curves upward and back. I just kinda guessed where I needed to start cutting the floorboard with a tape measure and a paint stick. I never thought until now to make a cardboard template of the shifter AND STICK to make it less of a guesstimate. Once I got the shifter in the car, it was just a matter trimming the hole big enough to clear the stick for reverse and the forward gears.

To do it again, I would make a cardboard cut-out of the shifter and stick - at least you can bend it around under the car! Well worth the effort for the fun of shifting a HURST on a 4-speed!!!

Good Luck, Tim

I'm not sure which shifter you need to make the stick part removable but here is the stick part

What are your gears and tire size Tommy? I was just thinking that a GEAR VENDERS overdrive would be pretty cool on the back of the Muncie!

GOOD pics Pete!

27 inch tires ,3.08 gears so I dont think my RPM's will be too bad at 65 - 70 mph...around 2500 to 2600 if all of the calculators are correct

Shifter in 1st gear with seat all the way back.

Mr. Gasket boot with trim ring under carpet.



Shifter works with lots of transmissions. There are two kits for Muncies depending on shift shaft type -- stud & nut, or bolt. Throw away the nylon bushings and use steel bushings.

My floor cutout is around 6"-8" long and 2" wide. The bottom of the shifter will protrude thru the floor in 2nd and 4th gears.

My shifter tower is a Hurst, but originally from a MOPAR Pistol Grip in a Challenger. I gave the shift lever to a MOPAR friend, drilled it for the bolt on style holes, as it was a push-in style originally, traded for the right shifter rods and arms, and then bought a Hurst P/N 238-8620 Tri-Five bench seat shift lever. Everything except the new lever were used parts. I can now unbolt the shifter lever from the tower and pull the trans with the shifter tower/linkage intact. All I really have in the setup is what the new shifter lever cost ($$$). I just could'nt see having to remove the shifter tower to remove the trans. Butch/56sedandelivery.

I'm pretty sure the 55-57 kit had had a bolt-on bench seat shifter handle back in the 60s-70s. It was much easier to install than the new welded-together setup.

Butch, will you post pictures of yours? I'd like to see how the shifter handle connects to the shifter mechanism.

The 700R4 is longer than the Muncie so you will need a new driveshaft. I don't remember the exact dimensions for the Muncie but the 700R4 is 30.75in and I believe the Muncie is about 3 inches shorter.

From the Hemmings website:

"On GM Turbo 350, 200-4R and the 700-R4 automatics, the transmission mount is the same as the one used for the Muncie."

If the input shaft has 10 splines, then the output shaft should be 27, same as your 700R4.

Good luck with the install. I took a Muncie out and put in a 200 4R and really miss the Muncie.

My digital camera is currently "T/U"; it's got 2 large dots in the viewer. I had to drill 2 holes for the bolt-on stick, as the shifter tower was originally a push-in stick with the MOPAR pistol grip. I also had to use a press to "squash" the reciever in a little and use spacers; it's tight/solid. Butch/56sedandelivery.

My shifter tower is an original factory equipment MOPAR/Hurst Pistol Grip that I gave the shift lever away on, drilled some holes, and bought the bench seat style tri-five shifter lever. The only number on the tower, other than the 3 patent numbers, is 6356. I've not actually seen a bench seat style shifter lever for a tri-five that was'nt a welded on stick; and was surprised to see they even made a bolt-on stick; bought it off E-Bay new. The reverse lever is longer and somewhat curved, but the reverse rod I used had enough threads to adjust it correctly on the MOPAR/Hurst. Butch/56sedandelivery.

Don't know if this will help ya much or not, but here it is:

I had an M20 I was going to use in the '55 gasser project, but then I ran across an early Doug Nash 5 speed in good condition, the Hurst shifter lever for that had to be cut just above the bolt holes and rewelded in a more forward leaning position to clear the bench seat. But it is positioned easily at hand for shifting, it's a comfortable position. The position of the shifter mechanism under the floor tunnel looks to me to be very close to if not exactly the same as the Hurst for the M20 would have been. I gave my M20 to a buddy who is building up a nice cruiser homebuilt 2,000 lb roadster with a mild 283, the M20 will be perfect for him. FWIW, here's a pix of how the shifter fit came out in my '55 with the Doug Nash and the bench seat:


The cardboard template is for the vinyl boot I sewed up for it. Here's how it looks with the boot installed before I put the seat back in:



The cord running up the tunnel from the shifter is for the line lock button mounted just below the shifter knob. It is amazing how many times I use that button to hold the car at a stop sign or a stop light when it wants to roll forward or backward while putting it in gear to get going. Way easier than working with the parking brake!

Good luck with yours, show us some pix as it goes in.
Aloha,
Willy

That statement would make people that don't know your history believe you don't know how to drive a stick.
