I'm using the nicely swept fittings. The 90 deg turns I can eliminate are in the front engine iron between the oil pump and the
normal engine oil outlet on the aluminum housing.

going to the front housing I could achieve a 10 + deg drop in oil temp.
due to higher oil flow and less friction.


Are you currently running nicely swept fittings like this:

or hard 90's like this?

It's entirely possible to see a decent change by going from hard 90's to
swept fittings. No drilling, tapping or otherwise rerouting anything.
