I prefer the Non wing version of asphalt racing. Davey Hamiltons wing series is getting fairly strong on the west coast. We usd to have the non wing 360 USAC series on the West Coast, and until the recession it was a strong series with 25-35 quality cars. Proved too costly to survive the downturn. Unrestricted 360 aluminum engines, Hoosier tires, as many as you like to use. CASA existed for a short time and was a lower cost alternative using American Racer tires. I think the USAC Western States could be resurrected if the iron block 23 degree head engine rule was adopted and also institute a number of tires per race rule. Meridian Idaho has a great budget class called Pepsi Sprints. 602 Crate motors, strict tire and weight rule.
