When I seen the Non Wing at Gas City 604s I didn't think Too Slow. Just not the power band of a SPRINT CAR. I mean I seen 305s with more torque able to pull the wheels. etc.

The 604s dont. and I think they gotta be flat footed to spin the tires for the turns.

Im probably way wrong and it seems to be growing at least getting people into a sprint car. So it may be a good thing overall. Maybe in a couple years they get a 410 engines and step up.
