My cam grinder recommended to use a good oil with alot of zinc and a small bottle of zinc additive. I have always used Valvoline VR1 racing oil and I add a small bottle of "Risoline" zinc additive. All I can say is I have only ever run flat tappet cams and I have never wiped a cam lobe. Ron

This thread is a good place to start: Moparts ZDDP thread For a more in-depth read: ZDDP article

I don't know if I have a flat tappet cam in my engine. I bought it in 2005 and it's a 64 block. No clue as to what the internals are. I don't want to add zinc and have it mess something up. Looks like it has a bit more than conventional Valvoline 10w30, but not way up there. .??? You've owned the car for 12 years and you don't know? You could simply remove a valve cover and inspect. I don't understand your last statement "Looks like it has a bit more than conventional Valvoline 10w30, but not way up there." At all.

Looks like it has a bit more than conventional Valvoline 10w30, but not way up there. Using a high-zinc motor oil will never damage an engine. The only things that they can harm are catalytic converters, which shouldn't be an issue for a '70 Monte Carlo.

I don't understand your last statement "Looks like it has a bit more than conventional Valvoline 10w30, but not way up there." At all. I'm not really good at some mechanical stuff. The price difference between ZR-1 and conventional isn't that much of a difference. I did stop by NAPA and talked to a guy in there and he said high mileage has more zinc, but according to Valvoline online high mileage (max life) has zinc/phosphorus% of .083/.077, conventional is .083/.076, and ZR-1 is .14/.13. Looks like ZR-1 has the most. I don't have the mechanical know how on lots of things, but wish I had learned more when my dad was working on cars. I usually take it to someone to get stuff done if I can't figure it out. I could call the shop that works on it and see if they know from what they've done on it. I wouldn't even know what to look for if I took off a valve cover to be honest.

Generally...the parts houses guys give out meaningless info, when it comes to zinc levels. They have no idea...
72 RR, Pump gas 440, 452s, 3800 lbs, Corked, ET Radials,. 11.33@117.72.
Same car, bone stock 346s, 9.5 comp, baby solid. 12.24@110.

Easy solution... As long as there ain't any cats, use an oil fortified with ZDDP... No worries...

Ok, one last dumb question. If I am using 10W30 now, would SAE30 be the same viscosity? I don't drive it in the winter. I bring it home in March/April and park it in October/November depending on when I can get it to the storage unit. It sits all winter and isn't started. Wife stopped at O'Reilly to look for me and they have SAE30 and 20W50. Site shows 10W30, but they don't carry it. Amazon has it for $34.77 for 6 quarts. 10W30 and SAE 30 are not the same, but you should be fine running the SAE 30.

Amazon has it for $34.77 for 6 quarts. 10W30 and SAE 30 are not the same, but you should be fine running the SAE 30. They are exactly the same, a 30 grade oil. The difference is as ambient temp drops, the 10w30 will act like a 10 grade oil. As the oil temp goes up, the 10w30 will GAIN viscosity. There is no reason to ever use a single grade engine oil. Ever.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston
