In the early seventies Isaw a farmall 40s to 60s est. year not sure of the model anyways this farmall had a chevy 283 ci in it. I have a dodge 225 ci slant six engine I would like to put in a farmall. does this sound realistic? or is this more hassle than its worth? I was going to look at an farm auction and find a tractor with a siezed up engine for scrap metal price. all I would do with this tractor is push a little snow and pull a small ditcher. I live in southern Idaho

Keep in mind that an automotive engine will turn much higher RPMs than a tractor engine if you "give it the gas" and this might not be good for the transmission and rear end gears.

John, This can be done. However, the time and money
spent to do it would be enough to overhaul the
factory engine about three times. Plus, you'd be
able to use the tractor much sooner! I have seen a Farmall C with a small block Ford
V8 installed. It ran and worked ok, but the thing
overheated really quickly. If you do swap engines
be sure the radiator can handle the new engine's
needs.

Good luck and just my $.02,
Phil

the only auto engine i have seen has been in the farmall F-20 and f-30 they have the paniterys on the rear drives ,they used to pull them in tractor pulls using the 283 327 and some even had the 348 cu. in.and they seemed to stand up very good . you can insall them very easy for they have a ujoint in front of the trans. sone even put a auto trans in front of the one in the tractor , which gave them a lot of speed ranges good luck with your tractor

Sorry My reply should have gone to John's question below
PS I have seen a Mopar 340 in an Oliver 88 and the owner had been pulling with it for some years.

John, when you reverse the polarity, the electricity still goes in the out the dist. and into the spark plug the same way it did before the reversal. Even the starter motor spins the same direction it did before reversal IF it is NOT a permanently magnatized starter, and I do not think any old tractors were. The elect. still goes into the starter the same way and "out" the same way. I got into a big and on going discussion with a young engineer friend who said if I changed the polarity (which I was doing), the starter would turn "backwards" It did not for the reason stated above. I have converted several tractors from 6v pos. ground to 12v neg ground, and reversing the polarity usually only intails changing the leads on the coil and the amp meter( so it show plus when charging--if you do not change, it will show minus when in fact, it is charging.

Years ago I saw a Farmall H fitted with a chevy 350 in central IN. It looked pretty nice. If you tried pulling hard with it I'm sure it would rip the gears out of it.

It won't necessarily be cheap, it will present engineering hassles you don't plan on, and the results may be marginal. Could be alot of fun, though!
