The 360s had their turn this past week, but it’s now time for the 410 engines to hit the Knoxville Raceway. Southern Iowa Sprint Week continues Sunday night with the second annual Capitani Classic. The race is named for longtime Race Director Ralph Capitani. It’ll feature a number of the biggest names in sprint car racing, acting as a preview for the action we’ll see starting Wednesday. You can hear the races live on KNIA/KRLS and streaming live on kniakrls.com. Pre-race coverage starts at 6:00pm, flag-to-flag race coverage starts at 7:30
