For maximum fuel economy on PTO work you will want peak engine torque at a little lower than the tractor's rated PTO speed so the tractor has some lugging ability. You may need a gear reduction or use the car's transmission to accomplish that.
Your Oliver 770 has a 216 cubic inch engine turning at 1750 RPM to make it's peak horse power at 540 PTO RPM. PTO speed on an Oliver 77 is even lower at what, about 1600 engine RPM? A car engine could have peak HP at over 4000 RPM and peak torque at 3200 RPM or higher. Slow that car engine down to only 1750 RPM to spin the tractor's PTO at standard 540 RPM and that car engine will be an under powered, gas guzzling disappointment compared to the original tractor engine. Install a 2:1 gear reduction behind that same car engine and the engine will run at 3500 RPM when the tractor's PTO speed is 540 RPM. Your will get a lot more power from the engine and it will still have some lugging ability.
To retain your live PTO, you may need to use the tractor's clutch instead of the car engine's clutch. The radiator's cooling capacity and and an engine governor are are other things to consider.
IMHO, I think you could trade the 77 or 770 for a nice 880, 1650 or larger tractor for less cost than installing a car engine in a tractor. Would overhauling the engine or replacing the clutch in a 1650 gas tractor still be a suitable project for you and the kids?

Today's Featured Article - Upgrading an Oliver Super 55 Electrical System - by Dennis Hawkins. My old Oliver Super 55 has been just sitting and rusting for several years now. I really hate to see a good tractor being treated that way, but not being able to start it without a 30 minute point filing ritual every time contributed to its demise. If it would just start when I turn the key, then I would use it more often. In addition to a bad case of old age, most of the tractor's original electrical system was simply too unreliable to keep. The main focus of this page is to show how I upgr
