I am no expert on this topic, but if the car has the thermostat in the fender well, I believe where the thermostat goes in the engine has an insert to let the oil flow without any restrition, and no moving parts.

I took apart a 1977 2.7 and that was what was there.

So and engine drop should not be needed.

I am just throwing this out there, so they may not be 100% correct.

Have a good weekend.
