Your claim that v engines require more cooling capacity than inline engines is confusing me. I might believe that heat management in a V engine is more involved. I can see why a v engine might tend to run a little hotter (which could mean less demand on the cooling system). What exactly do you mean saying a V engine require more cooling. Are you simply meaning that the greater surface area of an inline engine can radiate a little more heat directly into the engine compartment vs a more compact v engine?

I think you might be on to something regarding the difference in the engine compartment. My father in law just came by to pick up a trailer and I looked at the engine bay of his F350 versus mine.

I took that plastic upper piece off of mine a few years ago. Without it, you can get a better look at both sides of the engine. The driver side has a ton of room between the block and wheel well. I can literally stick a soccer ball or maybe even a basketball between there. The passenger side has the turbo so there is less room, but still has a lot of daylight. My father in laws truck was the complete opposite. I was hard to see daylight from either the top or bottom. So maybe it does have to do with more air circulation under the hood being able to removing heat off the longer and thinner block. How much of a difference that makes? Not sure.


EDIT: I was easily able to fit a regulation sized football between the block and fender well long ways (11 inches).
