FWIW Pennzoil 25W-50 Racing Oil has 1960ppm of Zinc and 1800ppm of phosporous. Quaker State Q Racing Synthetic is almost identical at 2000/1800
I haven't researched every oil available, but I've seen nothing higher than these two.

Stock or mild builds with flat tappet cams like at least 1200 ppm zinc. Major builds more, due to stronger valve springs etc.
I run 5W40 Shell Rotella T full synthetic which has close to 1400 ppm zinc. Most, if not all, heavy duty (diesel) motor oils have a good amount of zinc. Racing oils too, but may not be suitable for every day cruising. www.bobistheoilguy.com has tons of info.

Just found a bottle of Lucus additive at Advance for $12. It has zink and some other stuff in it "specially formulated for engines using flat tappet cams" It's a break in lube + additive.
Quote:They have two different products. One is an oil stabilizer/smoke reducer similar to 'motor honey'/stp, etc. The other is a zddp additive and motor/cam break-in product. It comes in a 16oz bottle and states that it is not to be used in 1994 or newer cars as it will trash the convertors. I used a bottle to break-in my recent 440 bullet in my sig car and just picked up another for an oil change.Quote:
