Took a poll at Indy during a rain delay and Mobil 1 was the choice of at least 2-1 over everything else in stock and SS. No consensus on viscosity.....10/30 works for us.

I have an IHRA crate motor Stocker, but oil preferences/applications should be the same for SS.

I use Amsoil 5w-20 Dominator all the time with great results. There are thinner oils as well. But you would need to ask engine builders what their preferences are for oil viscosity based on bearing clearances and reliability. Amsoil also has 10w-30 and 15w-15 in their Dominator series as well.

Joe Gibbs racing oil works best for me. Change every 25 to 30 runs. some guys go 50 runs, depending on set up...

It will work, but basically, it's too thick for most class racers. Thicker, higher viscosity oil robs HP and creates unnecessary heat.
