I think this wouldn't work as well as people think it would. .60s have more power, but don't rev as high and are heavier. Also, car engines are usually pushed to the limit, while plane engines are usually ringed and have conservative porting (there are always exceptions, of course.)
If something large were to be put in a car, it would also need to be designed for that purpose, especially in terms of heat dissipation.
This would be fun to try-especially with a 4-stroke
