292 with granny 4 spd into my 51 4dr?

Got the chance to pick up a good running 292 with a granny 4 speed. would it be pointless to put this trans in my 51 styleline? can i change the gears in the rear end to make use of the low gear or should i just pick up the motor and find a diffrent trans?

 

When I was a kid I ran a few with the truck tranny. Very seldom used grandmaw and it gave me 3 gears that were syncro (more or less).

It works for me.

 

Drop a 3.00 gear in the rear and ya done. That'll give you a useable first and a great 4th for highway.

 

good thanks. thats what i was thinking. i havent looked at the truck yet but anyone know if the 67-72 2wd 3/4 ton truck would be column or floor shift?
is there any way to adapt the shifter on the column in my 51 to this 4 speed?

 

Cool on the big 6 in the '51!

IIRC, the shifter in those years on the 4 speed was floorshift only. I haven't personally seen a 4-speed column shifter stock, but i have heard some guys running the stock column shifter for the 4 forward gears, with a secondary lever under the dash for Reverse.

Personally, I'd grab the motor only and find a car trans (T-10, T-5, even a Saginaw). But that's me.

 

If it's a four speed then it is a floor shift, however the three speeds were column shift.

You can shift the four speed from the column, provided you can make the stock linkage work. First will be in the reverse position and second @ the original first location. You will have to rig a seperate shifter for reverse, but it can be/has been done.

 

Don't do it.

That transmission is bulky in ways that may be difficult to adapt to the car and even with 3:1 gears you are never going to use 1st gear.

Sure grab the combination but put the transmission up for sale and get a trans that will work with your column shift.

I do not believe there is any way to adapt your column shift to this 4-speed. It is a top loader with the shift lever sticking up through the top.

 

Engine ya, trans nay... The 292 would be great in that car, but I would go for a T-5 and end up with four well spaced gears plus an overdrive for the freeway. Keep the rear gear in the mid 3's and all will be perfect.

 

I'm with Need louvers' there's a reason they call it granny. When you get done polishing a turd you still have a turd. Mike.

 

that truck trans will not work with any other hifter then the one that is on it. i alo don't think it will fit in the car. because they have a deep sump with gears to run a p.t.o. and it just mite drag the ground in your car. alo they bolt up different the a car. they do not use a slipjoint in the trans like a car does.

 

ok so does 300 for motor and trans sound fair? ill probably just pick them both up and look for a different trans like suggested. thanks for the help

 

If it was me I'd run it and start hittin up the local junkyards for AMC Eagles. Most of them came with either 2.73 or 2.35. I had an Eagle wagon with the 2.35 rear, real slow off the line but it got really good mileage. You could have decent pickup with the granny low (which would probably be more like a normal 1st gear) and an overdrive like final drive ratio.

 

Who cares what 1 st gear is, 4th is still 1:1 so you dont really gain anything other then shifting 1 more time or not depending if you use the granny gear.

 

I think I'm gonna get just the motor for 200

 

If you plan to run a manual try to get the bellhousing and clutch stuff too. No sense having to find it else where if you can get it with the motor cheap.

 

Another nay on the trans. Throw from 2nd to 3rd is like eighteen inches. Truck transmissions are best left in trucks.

 

and you have to be completely stopped to shift into first which would be a pain.

 

It will hang down pretty far. I saw a Dodge set up in a '65 Fury years ago and it was close to the ground. You could measure it up for kicks. I don't think you'd be happy with the set up after all the work was done.

With a bit of practice, it is possible to double clutch and shift into a non-syncro gear while moving.

But I agree with the folks who think this trans. is a poor choice for a car.

 

I would vote a no go on the truck "granny" four speed. Yeah with super high rear gears you can use low gear, but why? I had an old Ford with 2.41 rear gears and a NP435 and a 300-6, it would run 15mph in low but it was still in a truck. Other thing to think of is the weight of the "granny's", if you let it get away from you trying to install it on your back in the driveway, all your babies will be born with overalls on...

 

Tranny would be a little big for the car, $200 sounds good, get the belhousing, starter, clutch/flywheel with it, even if you have to pay a little extra. then I would go with any car 3/4 speed , and look for a 1970-1981camaro/nova/firebird rearend (they are pretty much a bolt in), so you can convert to open driveline.
I don't know if the 67 292 has a boss on the block to bolt a starter to, the one I have that is in a 65 truck, the starter bolts to the bellhousing... could be an issue if you switch to an automatic.

 

Will a Muncie Sm318 3speed fit this motor? If so will I need the bellhousing or will the one that's on the motor work?

 

got the motor and bell housing. but no trans

 

Looks pretty clean for an old truck motor...I had one that had 1" of grime ALL over it. Took a week of scraping it to get it clean enough to drop in a car. Blech.

Dunno about your question on the Muncie318 3spd...I'd guess the spline count is off on the input shaft...but I'm guessing. If you don't plan to build the motor really hot, I'd suggest looking for a V-6 Camaro/4spd. Those Saginaws weren't the strongest transmissions in the world, but unless you abuse them, they oughta hold together just fine for this motor. Or, the venerable T-5 swap...there are a couple of great threads on here that go into lots of details about that swap.

 

yes!!!! on the granny low, great for crusin slow, keeps the rpm's up so the exhaust will have the sound cool. nothing better than being able to drive ultra slow at cruz nights n shows

 

Lotsa good advice, but your choices are limited if you still have the torque tube driveshaft.

 

Get the engine. Dump the trans. The heavy duty granny four speeds (SM420 & SN 465) weigh 200 lbs. I know I shipped one to an Ebay buyer. Also in low gear cruising they trans will growl like a bear.

GM 3 speeds are cheap and plentiful, sometimes free. Be sure to get the bell housing as the heavy duty unit has a bigger index circle and the three speed won't fit w/o an index ring or the correct small index ring bell housing.

 

I use regular Muncie 3-speed truck setups in all my Chevies. Heavy duty, easy to change the clutch, etc.

The granny-gear deals were made to use with 4.57 to 5.38 rears.

Oh so true forddude, always thinkin

 

Not only that, you'll be geared right for pulling up the occasional stump. The granny gear trans is an excellent choice for a log truck, a school bus, or a wrecker.
