Want to put ether 283 or Chevy 350 in my 1939 M

looking for info on how to install a Chevy engine in my 39M and what id all need to get it done
Thanks

If your going to put and engine it it them make it and Engine , Why screw around with a small block stuff in a big block Big block fords Caddy's even a Chebby as will it be a bolt in , No not hardly but it can and has been done . Ya need to use the rear engine plate off the org. engine you can redrill the org. flywheel and make it work BUT myself i will not i prefer making a new Steel flywheel The org. flywheel has lots of heat cracks and can come apart and you never want to be around a exploding flywheel or clutch as it will come thru the center cast bell housing like a bomb. Takes a lot of measuring and figuring . Lots of lay out work.

it sure has been done a lot , most put a auto tranny in there with it . you would be better to ask this question on the pulling form .

Huh?

nd what's the deal on the "ether"? :shock:

And OH yea forgot ya need to add a gov. also . One thing to keep in mind is that a V8 in a M held down to 1550-1750 will not do what the old 4 banger would do for pullem power If ya bump the V8 up to say 2400 and get her out on the road in road gear your in for a ride and IF you get a little goffy and bump her up to say 4000 grand best hope your steering is tight and ya ain't never lived till ya ride a tractor at 65+ MPH . Had two that would sorta blow the hat off your head on the road . One Farmall 460 gasser with No gov. and a Oil all over 88 with a 390 four bbl ford . Smokey E bear did not see the humor of a tractor pulling two gravity wagons of ear corn down the road at 45 MPH .

The end use and how deep your pockets are will make a lot of difference of what and how.

Cubic INCH and long stroke .

Go with a Detroit more torque and less RPM and they already have a governor. 4V71 is a good one.

Keep the binder all binder and put an IHC truck engine in it.

Probably sipping on his bottle!

Just as well go big block..These pictures were taken at Bethany,MO in 1971..Both of these modified pullers had 427 Chevy's in a M Farmall chassis..

The "Magnificent M" was from Iowa and the M in the bottom picture was from Illinois..The Illinois M is still in the owners shed 43 years later..It was one high rpm 427...

this tractor belongs to a friend of mine

i keep hearing about putting Manuel transmissions on tractors when they convert them i can convert mine with out one right and if I'm just doing my for something to do not to pull with i can leave the rear end alone right I'm not looking to completely restore the tractor just thought since my motors shot and I'm in it for noting so i though why not toss a Chevy engine on it its not everyday you see a ole 39 M rocking a Chevy

I'll bet the gas gage looks like a speedometer!

I made a vow, long ago, to never criticize someone's punctuation again, but I must say - you forgot to put a period at the end of that sentence.

Good luck with your project. Keep us posted as it progresses. I always wanted to do something like that myself, and now I'm too old.

I think the extra transmission was to drop the rpm from the engine to the input of the old M transmission. That way the engine can develop near full power (approx 3000-3500 rpm)while you still get realistic travel speed. I am thinking some of the old (1960s-1970s) tractor pullers used an automatic transmission to get plenty of ratio off the line and then shift up to direct drive for the rest of the pull.

to physically fit the small block into the tractor, you will need an adapter plate to mate the rear of the engine to the front of the transmission. Not being familiar with the M I don"t know what is involved. I do recall a similar swap years ago where the outer flanges on both sides of the block were cut off so it would fit between the stock frame rails.
The other 3 issues:
1. gotta mate the M clutch and clutch shaft to the Small block flywheel. This probably involves at the least drilling new holes for the pressure plate and changing/boring out the pilot bearing in the rear of the crank.
2. Then you have to support the engine near the front end with mounts of some sort.
3. And you have to get the radiator hooked to the engine somehow.
That will get the engine in the tractor.
Then:
If you want to work it, you will have to install a remote governor and work out the belt drive to it and the linkage to the carburetor. Be prepared for ssome serious fuel consumption.
