CAR ENGINE IN TRACTOR ??

If you just want to use the 413, it could probably be done. You will likely wind up with about 2 or 3 times the torque that 77 was ever meant to take in its driveline but it may take it, at least for a while. Also, even stock that 413 will wind up to three times what that Oliver was geared for unless you get a governor on it. Should really make short work of cultivating the old corn field.

An in-line 6 of some sort (like a Chev 292 or Ford 300) would probably be more appropriate.

If true you may wnat to change the camshaft, manifold and carb with one that came off this tractor. it might help with the low RPM HP.

You can put almost anything in it if you have enough time, patience, engineering skill, and money. I've seen old flathead Ford V8 engines in old Ford tractors, Chrysler Hemi engines in Farmalls, and Chevy 454-inchers in Masseys. I went to college in the early '60s with a guy who made a few bucks in the summers putting Ford 390 and 406 V8s in Farmall M tractors. Seemed to be a pretty good swap.

Cooling can be a problem if the radiator isn't in really good shape, and (as noted in another post) you may need to speed up the water pump if possible. Tractor engines generate maximum torque at lower rpm limits than most car engines, so you'll need lots of cubic inches to offset this problem. One souce of governors for this would be gas combine engines, as some of the older ones WERE car engines! Be advised that you can easily put together something that will run faster than your brakes can handle!

Most older tractors are designed to provide rated PTO speed (540 RPM) somewhere in the 1500-2000 RPM range, give or take a bit. You need to match this with whatever engine you put in.

The new engine must be governed in some way so the RPM stays relatively constant under changing load conditions. There are after-market belt-driven governors available that should work.

Also, be aware that the HP rating of a car engine is usually at a much higher RPM than you would normally use in a tractor. Also, a car engine very likely won't make as much torque at lower RPM (that 1500-2000 I mentioned) as a tractor engine.

Finally, be aware that the higher RPM and greater horsepower of that big ol' honkin' 413 may raise all sorts of problems with the transmission/bull gears/rear end of a tractor. Don't know about the Oliver 77, but it may well be rugged enough to handle it. Just something to consider.
