KNOXVILLE, Iowa — Knoxville Raceway officials have announced a significant purse increase for the Knoxville Championship Series 410 sprint car class and the approval of aluminum engine blocks in the 360 sprint car class.
For the upcoming season, Knoxville Raceway will boost the start money for the weekly 410 feature. Starting payouts will increase from $700 in 2024 to $1,000 in 2025. With this adjustment, the total weekly purse for the division will rise to $41,890.
“This increase is a testament to our race committee and Fair Board’s commitment to reinvesting in the sprint car racing,” said Race Director John McCoy. “We’re fortunate to have the support and resources to make this happen, showing our appreciation to the dedicated teams competing here each week.”

360 Engine Rule Change
For the past three seasons, Knoxville Raceway officials have been working on the potential implementation of aluminum engine blocks in the 360 class. Historically, only steel blocks were permitted. Both steel and aluminum blocks beginning in the 2025 season.
“There has been a growing concern from teams and engine builders over the rising cost and availability of steel blocks,” said Race Director John McCoy. “This new aluminum-block rule does not limit to any one manufacturer, permitting teams to use new or used blocks from any source. Aluminum blocks offer the advantage of being repairable, which can help manage costs for our race teams. Skip Jackson and Mike Proffitt have been working on this project to keep the additional weight placements safely within the engine compartment, helping to offset any weight advantages of an aluminum block.”
Looking forward to 2025, our 72nd season of weekly racing begins with the NOS Energy Drink World of Outlaws on April 18 and 19, followed by the Pella Motors/Kraig Ford Season Opener on April 26.
