Engine Swap
I'm not sure if that last question mark means you want me to explain why I said
it is likely that the assumption is wrong, or something else. Assuming the former, my basis is empirical - it can easily be shown that a typical pusher with side-mounted radiator will quickly overheat if there is not a very large booster fan to suck lots of air in. Any natural flow is way too weak. In my case, just going down a flat road with the fan idling at 600RPM I see about 1 degree of temperature rise per 5 seconds until the fan kicks into high speed.
