Out here in Northern California I run in what we call "Wingless Spec Sprints". It's a self starting 360 class. Not a crate motor but we have specific rules, with one track being different then everyone else. It's stated that the starters help speed up the show, but I believe the main reason was to help limit compression as starting a sprint car in gear takes some oomph. Don't start on your own, get pushed and start in the rear.
It's marketed as a "budget" class but still got guys with $15-20k motors.
Even running Calistoga a couple times a year now...
