Re-power F20

I remember back in the early 60,s there were several F20,s and some F 30,s that the farmers had installed 6cyl motors out of IHC 190 trucks. They were 6 cyl motors
and gave more HP. Do any of you folks recall that being done.

Just a question
 
I have heard of and seen pictures of different engines in an F-20. Not specifically IHC 190's.
It'd be fairly easy to do on an F-20. There is just a shaft running between the clutch housing and the transmission. And the transmission is not connected to the engine/clutch housing in any other way other than that one shaft. An engine that could be swapped in along with it's clutch would be real easy to do. One that requires it's transmission case for operational clutch and mounting would be more complicated.
 
Never seen an F20 with an IHC 6 repower. But I have stumbled over these with a Chevy 6 and a Cummins 5.9 shoehorned in. (The F20/Cummins is an impressive puller!)

Im the mid 50s my dad inherited his dads 52 Chevy car and a f20 along with everything else. The car got totaled shortly after and dad put the 6 cylinder and transmission in the f20. That was about 1957. Used it to plow with 3 -14s instead of using his M. Turned out to be smoother, more power, and less of a gas drinker than the M.
 
A 52 chev car had a 216 splash oil system,which wasn't good, i don't see that as a good tractor engine, with a 4 quart oil pan, and maybe a add on filter!1 Sorry
 
fastfarmall: Don't get me wrong. I didn't claim it was a great creation, it was just the best running and most powerful F20 in the area in 1957.(lol) The post asked if it has been done.
 
Neighbor started out with a GMC V6 with a 4 speed in front of the factory transmission, Then he switched it up with a 409,dual 4 barrels. It never pulled a plow, but he did pull it under the name of Dirty Old Man. (early 70s)
 
I'd heard of different engines installed in early tractor pull, but never saw any pull.

A small contractor that I worked for one summer in the mid-1970's had scaffolding mounted on an old F-20 or F-30 tractor. To improve the road speed he installed a Oldsmobile nailhead V-8 with an automatic transmission ahead of the tractor transmission. The steering was so loose that no one was willing to drive it between job sites so it stayed parked behind the shop.
 
I have two repowered F12.One has a 4 cyl flathead (military)Jeep.The other,a 2.8L V6 from BroncoII.The Jeep engine has the 3sp trans hook to a short driveshaft.The V6 ,O built an adapter to plug directly onto the clutch,elimanateing the need for an extra trans.I know of a F12 in the next town with a 6 cyl Chevy.
 
Ss55,the V6 powered one is my puller at the local tractor pulls.Makes lots noise and dust.The crowd loves it! We call it thr 'Rat tractor'. :)
 
That is my kind of a fence row! How was the v6 conversion for a working tractor? Looks like you gained weight and traction with the rear tires but my stock F12 and F14 always seem light and underpowered, use the fast hitch super Cs a lot more for raking and odd jobs. Mike
 
DELTA RED - Neighbor had an F-20 that had been a hot-rod pulling tractor before He got it. It was his HOG chore tractor, it would run his mix mill to grind hog feed if he didn't feed the corn too fast. I had fantastic road gears, I Think there was a transmission between the Big Block Chevy and the stock F-20 4-speed. It had pulling headers with upright collectors, BIG Holley 4bbl, had a nice lope at idle.

That little Ford V-6 you have is probably the 2.8L German V-6. Great little motor. I wanted a Bronco II so bad when they first came out, my buddy had one. I had a hill in East Moline,, Ill on Kennedy Drive right off John Deere Road, The Bronco 11 with 5-speed manual I test drove up that hill was faster than my '88 Ford Mustang GT H.O. 5.0 & 5-speed manual, my 3.08 gears hurt me. My '79 White Road Boss 2 with 320 hp 903 V8 Cummins 4.44 gears and Spicer 6-speed was my 2nd fastest up that hill, bobtailing. 56 mph @ 2600 in 5th gear.
 
A guy that comes to our tractor club's show has a B Farmall that's had a 266 or 304 IH V-8 truck engine grafted to the B's bell housing. (I don't know how to tell the difference between a 266 or 304.) It's a show piece only. He said he's never had it hooked to anything. It's such a good job that it looks factory.
 
The V6 is not a working tractor.It is strictly a puller.The fully restored F12 would actually pull more wt because it pulls till it runs out of power.The V6 gets out there and just spins and jumps.The V6 engine has to be wound up to have any power.At low speeds it just falls flat.But it puts on a better show.The weight of the two is almost exactly the same.
 
I saw a f-20 at the auction in Ohio that appeared to have an older 6 cylinder Chevrolet truck engine. I should have bought it. Have seen a couple of F-20s there with the IH 345 V eight. Non were running.
