Before jumping on the synthetic bandwagon I suggest reading the articles written by dnewton on the home page.
First off consider how the engine will be operated and under what weather conditions. Most every sbc engine will do just fine on a 30 grade oil. Now if it's a summer car a 10w-30 shows great used oil analysis' and if you are going to use syn Amsoil's sso line shows to be nearly shear proof in even the most demanding applications.
I like the pennzoil line of oils. I'm using pennzoil platinum in my hemi right now and have no issues whatsoever.
Do you have an oil cooler. If so I would consider trying a 20 grade. As pong as you have 10 pounds per 1000 rpms of oil pressure that's more than adequate. Remember your oil pressure gauge shows how resistant to flow your oil is and thinner oil actually has more volume going through the engine at any given speed.
I think we need to know more about how this engine will be operated before an accurate and suitable recommendation can be had.
But in a performance engine I would go with royal purples hps line. It has elevated zddp levels and red-line is another fine choice however you could be just as well served with pennzoil yellow bottle.
Remember,synthetics don't really shine unless you are extending the oil change interval or you are putting the engine under serious stress,like auto-cross,or it will be operated in extreme cold. Otherwise,as dnewton's articles show,a conventional will be more than enough protection.
You really should read the articles on the front home page. They will bring you to a point of actually understanding what alot of our members are going to say. They will help you to know what the heck these guys are saying,and they are a wealth of info.
And welcome to bitog.
It's a torque truck. 330hp, 550ft lbs torque. Used to haul between 2000-5000 in the bed, hauling a triple axle horse trailer. Temperature swings from -10 to 110 sea level to 10000 ft. Synthetic oil resists the breakdown a lil better than conventional hence why its used in my other vehicles. My vehicles are driven hard.
If you're looking for an oil that will provide protection year-round under those operating conditions, you're definitely looking for a top-quality synthetic. Redline, AMSoil Z-Rod, Joe Gibbs Hot Rod 30, and Royal Purple HPS are all high-zddp full-synthetics that would do the job, but since you don't want to send away for a boutique oil, those seem to be out of the question. Rotella T6 would be a good choice, but it is a mixed-fleet diesel oil that has a large amount of Magnesium-based detergents, which are not necessarily good for a heavily-loaded gasoline engine.
For someone looking for a readily-available high-zddp oil, I normally recommend Valvoline VR1 10w30, which is available at most NAPA's. The problem is that VR1 is not a synthetic. I think it would work well if you have an oil cooler and oil temp gage on your truck, and can assure that oil temp doesn't exceed 285F.
The next possiblity is to buy a low-zddp SM or SN-spec synthetic oil that is readily available, and use a zddp additive to boost the antiwear capability. ZDDPlus (and others) are available for this, but you're buying an expensive synthetic, and then increasing its cost by adding an expensive additive. By the time you have done that, you should have just bought the expensive boutique oil.
Brad Penn makes a unique 0w30 semi-synthetic oil that has all of the zddp you need, but I don't know if it is readily available in New Mexico. I think that it is mostly available in the eastern half of the US.
My personal favorite is Redline 5w30.
