Anybody using Driven brand HR-2 oil in their slant?

Nope, he's wrong about that. You'll see and hear all kinds of handwaving and spooky ghost stories about how y'just cain't get oil that'll protect an old engine at the parts store any more, so y'gotta-gotta-gotta buy this, that, or the other special boutique oil. Horseshіt! The worst oil available today is leaps and bounds better than the best available 10 years ago, let alone in 1974 (or '84, or '94). Use any reputable brand of 5w30 oil in your new engine (there is no reason to avoid synthetic, but your engine doesn't require it), and a good quality filter; change the oil and filter at reasonable intervals, and scratch this off your list of stuff to fret about or spend unnecessary money on.

Good, dependable education on the matter here, and more discussion here and here and here and here and here and here and here.

Thanks, Dan. I just read your reply above and all the attachments you added. I know this engine oil topic has raged for years and I agree we're probably over-thinking it. My experience with the slant six engine goes back to 1977 when I bought my first car - a 225 powered 1974 Duster. People beat the snot out of these cars back then. The maintenance by the high school and college kids that drove them was spotty at best. They'd go much longer than the recommended interval for an oil change. They'd use cheap oil and crappy filters. And the motors kept running just fine. I never tore one down and checked the tolerances with a micrometer after this poor maintenance because I didn't have to. It wasn't the engines that killed these cars, it was rust. They would simply rust apart and go to the junkyard with an engine that still ran pretty well. So I think that your recommendation is spot on. Here's the oil I get at NAPA - around $12.00 for the five quart jug when it's on sale. I use the NAPA Gold #1068 filter as previously mentioned. My expectation is that this amazing (and now professionally rebuilt to zero time specifications) piece of engineering that the Chrysler Corporation created in the late fifties will run perfectly for the next 150,000 miles as long as I change the oil and filter every 3000 miles.

Any final thoughts on this?
