Any modern oil will have more zinc and better additives then the oil had when your engine was new. The reason to use dedicated Muscle car oil ( high zinc ) today is most have heavier valve springs and different camshafts. Stock engines with stock valve springs are just fine with a good name brand oil. VR-1 is a good oil, doesn't cost to much more and is easy to get. PennGrade is also a good oil but cost is higher and isn't available everywhere.
10w30 NAPA brand full synthetic is what I run my 250, been using it for 25 years.
