The 18-year-old, who made his classic debut in 2018, has inked a deal to drive for National Sprintcar hall-of-famer Guy Forbrook in the American summer.

The deal has curtailed Scelzi's Australian plans.

Scelzi's exit has left nine American drivers to vie for classic honours.

Former winners Tim Kaeding and Shane Stewart have committed to race, while high-profile NASCAR star Kyle Larson will also hit Premier Speedway.

Cory Eliason, Kalib Henry, Buddy Kofoid, McKenna Haase and Carson Macedo are among the other US-based drivers set to race.

In other news, West Australian Jason Pryde will pilot the W60 car.

Scelzi's withdrawal and Pryde's switch mean the entry list is at 107.

The three-night event begins on January 24.
