Take the time to put new gaskets on, the 1st time I put it in my 440 I did not and I had a heck of a mess. I also use 3M weatherstrip adhesive as a sealer.
ok,,, thanks...

I have been using Penzoil 10w30 full synthetic with Wix filters for over 10 years.
It is hard to keep the motors sealed. Synthetic does tend to find a leak.
Why does divorce cost so much?
Because it is worth it!!!!!

AmsOil makes a great 20W50 Full Synthetic Racing Oil that I have used for many years in 440's. I live in the South, with many days of 100+ degree weather, so I prefer the heavier 20/50 blend. New motors need adequate break in on standard oil first, to prevent ring break in problems (AmsOil lowers friction to the point that new rings may not seat). It also cleans up gunk in dirty engines, so a good engine flush should be done first, followed by gasket changes when leaks appear on older engines.

You can use safely use a synthetic oil for your 440 but 15W-40 is a conventional/dino grade of Heavy Duty Engine Oil (HDEO). HDEOs have higher levels of phosphorus (the antiwear component of ZDDP) than Starburst Oils and a CI-4/SL HDEOs generally have the highest levels of phosphorus. If you're using 10W-30, you can also use a synthetic 30-weight HDEO but these are generally 0W-30 and 5W-30 grades because synthetics flow extremely well at low temperatures. Being a synthetic, they also don't thin out as quickly as a straight SAE 30 or 10W-30 dino oil. Heavy Duty Engine Oils

Fact: An SAE 20W-50 conventional motor oil flows the same as a SAE 20W-50 Synthetic motor oil. If they are both rated with the SAE spec. then they must flow the same at engine operating temp. Now if we are talking cold temperature flow, synthetics almost always flow better than conventional oils in cold temps. Fact: Synthetic motor oil does not cause leaks. Leaks can occur any time you change brands or types of motor oils whether it be conventional or synthetic. Some motor oils can leave behind deposits which can act as a supplemental seal on higher mileage engines. If your main crank seal is bad and you have gunk protecting it from oil deposits, then you probably have no-or-minimal leaks. Now you switch to another brand; it could be conventional or synthetic, both of which have differing levels of detergents and other additives than the oil that you were just using. These differing additives eat away at the gunk that was acting as a supplemental seal and now you have a leak. The issue was not the oil change, but rather a worn out crank seal. Fact: There are many synthetic motor oils that have the same or higher levels of Zinc and Phosphorous as Heavy Duty Engine Oil (HDEO). Example:

DennisH is not talking about On-The-Shelf-Retail cost as you saw at Napa. He's talking wholesale cost.
