I'm not very familiar, can someone tell me the difference between these and 305 RaceSavers? Other than the engine being different. What's each car cost as a whole?

Wouldn't it make more sense to run 305s?

No other tracks even close to the area are slated to run these new sprints (at least not that I've heard of) whereas I know there are 3-4 tracks in Indiana that have 305s on their schedules for at least one or multiple events this year.

Hopefully it works out for them.
