What I gather Wisconsin WingLESS can run either a 604 crate or an iron-head spec motor. They're both mandated to 450hp max but I'm thinking the extra 50lbs on the nose would be a huge disadvantage to the spec.

I'm also curious if anyone here has experience with a carb on a Sprint Car. I'd think there'd be mid-corner stumble problems from the float bowls sloshing over.
