A 408 is 12% more cid than a 365 so a 365 would need to turn about 12% more rpm. Also which would be similar piston speeds for both, so even if you took both engines to max piston speed both engine would be able to displace the same amount of air (cfm).
It's like say I ate 14 tacos all the way. Could my butthole and more importantly could the noses of those around me handle another 12%? It's a question we may never have the answer to.
