The Chevrolet R07 engine development has progressed to the point where up to six teams are expected to run the engine at this weekend?s race. Cars anticipated to debut the new Chevy engine are: Hendrick Motorsports teammates #25-Casey Mears and #5-Kyle Busch; #20-Tony Stewart and his Joe Gibbs Racing teammates #11-Denny Hamlin and #18-J.J. Yeley as well as a fourth Richard Childress Racing entry, #33-Scott Wimmer.

After more than 50 years of successful race development of the Chevy small-block engine, GM Racing has developed its first (for NASCAR competition) purpose-built small-block race engine, the R07. The engine will debut Sunday at the Samsung 500 Nextel Cup race at Texas Motor Speedway.

A brief presentation by Director of GM Racing Mark Kent, followed by a Q&A period with Jim Covey, NASCAR engine program manager, is scheduled for Saturday, April 14 at Texas Motor Speedway.(GM Racing PR)

Hopefully they have worked out the lubricating and cooling issues that came up with this new engine when Scott Wimmer unsuccessfully tried to qualify a car with this engine earlier this year...
