Overton’s 400 Team & Manufacturer Stats

Chevrolet and Toyota have been dominate at Chicagoland Speedway, but Ford and Toyota have been dominant all season long. With the dominance of Ford this season, it is hard to look at these manufacturer statistics to say who has an edge.

Overton’s 400 Predictions

Chase Elliott, how drives a Chevrolet, has had a very good record in this two visits, but those driers in Toyota and Ford have been difficult to stop this year. The dominate duo of Kyle Busch and Kevin Harvick sit right behind Elliott in this weekend’s power rankings; can Elliott hold them off and finally end up in victory lane?
