Most any quality 5w-30 synthetic motor oil will do. The articles below will give you plenty to think about. Many others like that on the internet.
https://540ratblog.wordpress.com/201...-test-ranking/....note that M1 5w-30 ranks high on this list (not necessarily the other M1's).

Not all that much difference in ratings and additive packages among many of the usual brands of motor oils.

Many UOAs have shown LS1s to respond well to oils on the thicker side of a w30 or the thinner side of a w40. I've been using M1 0w40 in mine for over a decade now with good results.

This is an important consideration IMO, as the majority of wear that a typical street engine will experience is due to cold starts.

I would use 5/10w-30 synthetic oil. Make sure it says GM4718M spec on back label, Dexos1 also is a newer spec that replaces GM4718M. Thats the Corvette/Cadillac spec that proves it can handle the heat properly without breaking down. I know Pennzoil Platinum at wally world is the cheapest oil that meets that spec. Other options would be Mobil/Castrol etc. If it doesn't have that spec I wouldn't buy it. I know Pennzoil platinum is about $25 for 5 quarts, Mobil and Castrol are about 2 buck more. No need to try some questionable thicker oil or snake oil, if it meets the spec your golden. If changing to one brand caused ticks or something you have a problem far greater then the spectrum of oil, given that it was the right weight and type.

Again, there is certainly nothing wrong with using oils that meet current GM specs and fall within the grade rating listed on your oil fill cap, and for the vast majority of users this will be perfectly adequate. But it would be false to assume that there aren't potentially better options and/or that every oil within that range will show equal wear results on a given engine.

I figure most people don't want to play trial and error with different types of oil on an expensive motor. I am just pointing out what it's suppose to take according to GM. I doubt anyone has who has ran the recommended oil and changed it regularly has ever had an oil related engine failure. BITOG is a interesting site with useful information, but many people worry about the smallest details in the oil that you will never notice, the key is remember to change it.
