Corey Heim is set to make a notable change when he moves into a full-time NASCAR Cup Series role with 23XI Racing in 2027. After running part-time in the No. 67 car, Heim will instead use No. 35 for his full-season entry with the team.
The number swap adds a new detail to Heim’s rising profile after his strong part-time results in 2026. The Brickyard 400 winner has also collected two Cup victories for 23XI Racing, making his eventual full-time move one of the more closely watched developments for the organization.
Heim has made it clear he does not want the No. 67 to define his long-term Cup career, with the number described as a poor fit for a full-time identity. Moving to No. 35 gives him a different look as he prepares for the next stage of his NASCAR career.
The move also continues the growth of 23XI Racing, the team owned by Michael Jordan and Denny Hamlin. As Heim transitions from part-time appearances to a full-season Cup campaign, the number change helps mark a fresh chapter for both the driver and the organization.
