High volume oil pump 98 K1500 5.7

I disagree that an oil cooler is prudent here. Oil wants to be at or above the boiling point of water, so how hot was it? Not only that, if the motor shells out the new cooler is ruined.

What oil filter are you running?

My hot idle pressure increased ~10 psi on both the 350 and 383 when I put the stock cooler setup on it. My oil temps will get close to and even over 300°F in summer without towing anything.

My point exactly, you actually know what your temps are instead of arbitrarily slapping a cooler on as a bandaid.

Maybe try a Wix. I've used nothing but Wix for years. I put in that same AC Delco and within two weeks had 20psi with a rod know. I was running upper 20's before that

I only run Mobil One filters. They have a good anti-drainback and more filter media.

Wix "was" a great filter and company. They've been bought-out by Mann + Hummel.

Now there's no telling where Wix filters are made until you're holding it in your hands. USA...Poland...China...Mars.
