I don't know about Alky. But I run Valvoline VR1 Racing 10W30 in mine. You can find it for under $5 a quart. The zinc and phos levels are pretty for an over the shelf oil. And I buy a bottle of Lucas Oil Break In Additive. It's a zinc additive that can be used for engine/camshaft break in (use the entire bottle), or as an oil additive to raise zinc and phos levels high enough for solid lifter motors. For my 6 quart oil pan I use 3 ounces of the additive.

Look at Spectro Semi-Synthetic oil. Added zinc for flat tappet cams. We use on alcohol and have had very good luck

And I don't see anything on their site about what is in their oil.

I like Kendall oil and use it in all my street cars, but it doesn't have enough zinc and phos for me to feel comfortable putting it in a solid lifter motor. Unless you were mixing in an additive. Kendall has a great site, their product sheets show a lot of info.

Off the shelf the VR-1 had really high levels at 1500ppm, and its easy to find. And there is a general consensus that 1500 to 1800 is the bare minimum for a flat tappet engine. 2000 being ideal.

Here is a good oil site.
http://www.bobistheoilguy.com/

They have a great forum that talks about oils, and tests them; posting the results. Just scroll down to the Oil Analysis Reports. Here is a quick link to several types of oil tested.

Brad Penn oil is what my engine builder recommends. Less than $40.00 a case

Central Pa. About an hour and a half away from the refinery in Bradford Pa. Last case I bought was at the beginning of the season. Might have gone up now.

Ditto on the Brad Penn oil. Used to run Valvoline, like the Brad Penn better.
