You can get a dozen different recommendations on types of oil to use, back in the era of your truck SAE 30 was common. For now in my 478 I'm using Shell Rotella 15W-40 that's for Diesel truck engines. I'm using it as a break in oil because of it's zinc content and most likely will keep using for some time. I may try synthetics after the engine is well broken in after 5000 miles.
