Muncie 4-speed
Is anyone running a Muncie 4-speed in our trucks? How is it set up? Where does the shifter come through the trasnmission hump? (Forward, rear, middle?) What type of shifter do you use? I have a lead on a Muncie for $450...
We are kicking around ideas for a build and want to know what type of non-granny 4-speeds we can use behind a built 350 (around 400hp). I think the NV4500 5-speed could work, but would like to have something a little more close ratio. |
Re: Muncie 4-speed
Hurst makes a shifter and install kit just for putting muncies in trucks.
I have a super T-10, but the muncie should be identical - Here's pics of mine: http://www.personal.psu.edu/jxu109/truck/int1.jpg http://www.personal.psu.edu/jxu109/truck/int2.jpg |

I had one in my first '67 stepper but I used the stock column shifter and used a choke cable under the dash for reverse...:) LockDoc |

Here's mine. Sorry the pix is so dark but it was in the shade on a bright day. It's hard to see but mine comes out of the center of the hump far more forward that JIM_PA's does and yes, mine is factory original.

Here are some pictures of my 67 Pickup.
454, Muncie 4 Spd, High Hump Tunnel, Original Buddy Seats. The picture with the stick closest to the seats is with the transmission in 4th gear. http://i107.photobucket.com/albums/m...d/CIMG0866.jpg http://i107.photobucket.com/albums/m...d/CIMG0873.jpg http://i107.photobucket.com/albums/m...d/CIMG0874.jpg http://i107.photobucket.com/albums/m...d/CIMG0876.jpg |

Not much....just a simple ole '69 ruck crushen M-22!!! Will not fit through the original hole. I got another high hump and custom cut mine to fit nice and tight. She's sweet!

Re: Muncie 4-speed
The shifter comes out the same place a 3spd floor shift conversion does.It`s 100% bolt-in swap for a 3spd.

Re: Muncie 4-speed
I have a really rookie question. I have a 3 spd converted to a hurst floor shift. If I go to a muncie 4 spd, since the shifter comes up in exactly the same spot, can I just reuse the actual chrome stick I have since it works with my bench seat?

Re: Muncie 4-speed
Will a 4spd work with a small hump floor? Or does it need to be converted to a high hump?
|
Re: Muncie 4-speed
I have a small hump. Are you talking about a car or truck 4-speed. I think it matters.

Re: Muncie 4-speed
Hey Jim....what's your shifter arm out of? I think mine was a car (Impala) with a bench seat and I had to do a little fabbin' to get it high enough to clear the seat.
Special K: So you're telling me that a 3 speed is that close to the driver's side? I didn't know that. Mine was a 4 speed and the hole was dead-center. Not even close. Seems like the rake and what not of your shifter arm might affect clearance. Then again....those factory holes are usually pretty big! |

The Hurst (Indy) 3spd shift levers bolt up different than the Hurst 4spds.I forget the series,Competition?I don`t see why they couldn`t be made to work.I have a tall Hurst 3spd lever I had in a truck that I hope to use.There is a just for our trucks application now.I know the 55-57 car bench seat levers work and I know of another that doesn`t have such a hook to it works.I just don`t know what it came out of. |
Re: Muncie 4-speed
What year model, transmission from car would work in our trucks?

Just make sure it's a muncie, or SUPER T-10. Watch out for Saginaw 4 speeds, you probably don't want one of them. |
Re: Muncie 4-speed
Yep with the HP Hurst shifter
There really is no other choice.... 67 Chevelle was the motor tran donor |
Re: Muncie 4-speed
I had just written a long drawn out explanation of this and just as I was about to hit submit......my electricity flashed off for a few seconds.
So, long story-shortened These car transmissions really do not have enough span between low and hi gear. The close ratio box is only 2.2-1 and the wide ratio is only 2.5-1. Where your typical truck transmission, not even counting that super-low first gear, has about 3.5-1. If you gear the rear differential high enough to run at hi-speed on the highway, it will be a slug in the city....and forget about hauling or towing. If you gear it low enough to be "fun" to drive in town, it will run out of breath on the interstate. You can't have both |
Re: Muncie 4-speed
Right - this is definitely more for high performance/cruisers, rather than heavy towing.
I do fine with the 295/50/15's and 3.73's, and I can still haul more weight than I would ever attempt to haul with it, but I wouldn't do it all the time. A car transmission just isn't made for it. When I need tires again, I'll probably go to a 275/60 but that won't change things much. |
Re: Muncie 4-speed
I don't do much hauling with mine,mostly trash to the dump.

Most of them are called by number SM420, SM465, etc. Besides, you wouldn't have to ask or "adapt" to use a factory availble transmission. |
Re: Muncie 4-speed
Tremec TKO all the way - 3.27 1st gear, .68 OD 5th, shifts like butter, and tough as nails! with that 400hp and a set of 3.73's, you'll never stop smiling!
