That's been done quite a bit, according to my information. The two big things to consider are RPM's and how to govern it. 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.
