Chevrolet has not received an official request from Dale Earnhardt Jr. to swap race cars with Honda driver Graham Rahal.

Earnhardt and Rahal are both sponsored this year by Army National Guard, and Rahal reached out to Earnhardt last week via Twitter to see if NASCAR's most popular driver was interested in swapping cars.

The Twitter conversation sparked tons of fan interest, and the guard said it wants to be part of a swap. But Earnhardt quieted the talk two days later when he said he could not drive a Honda. Chevrolet and Honda are direct competitors in the IndyCar Series.

Chevrolet's Jim Campbell said Saturday the manufacturer would look at any proposal to drive an Indy car from Earnhardt with "an open set of eyes."
