USAC Southwest Sprints Aligns Rulebook To Allow 410 Engines, Increased Purses In 2019

The United States Auto Club (USAC) has announced that the Sands Chevrolet USAC Southwest Sprint Car Series will open up its rules package to include 410 cubic-inch engines beginning in 2019.

The move now aligns the series with the same rulebook as the USAC AMSOIL National and CRA Sprint Car Series. Although 360 c.i. engines will remain legal to run with the series, the rule change will give the series a major boost heading into the future.

“The tradition of both USAC and Arizona Sprint Car racing is with 410 c.i. engines,” Series Coordinator Chris Kearns said. “More and more Arizona-based teams have been purchasing 410’s of late and this move is going to bring new life to the Southwest Sprint Car Series in 2019 and beyond.”

The Southwest Sprint Cars will also now feature a raised purse for each race, paying a minimum of $2000-to-win and $250 to start. Additionally, the USAC/CRA events at Arizona venues will now be co-sanctioned by the Southwest Sprints and will have an increased payout of $3000-to-win and $400 to start.

Furthermore, beginning with the 52nd running of the “Western World Championships” at Arizona Speedway in November 2019, the main event will now have the Southwest Sprints competing with the National Sprint series.

Throughout its history, the Southwest Sprints have been a primarily Arizona-based series, with a handful of races this year at locales such as Nevada, Arkansas, Oklahoma and Kansas, but in 2019, the series will head to California’s Perris Auto Speedway.

The Southwest Sprint Car Series is currently in its eighth season under USAC sanction.
