Just when we thought that the horsepower battle between Ford Mustang and Chevrolet Camaro had reached its zenith with the 662-horsepower Shelby GT500, it appears that Chevrolet won't go down without a fight. Based on an official-looking Vehicle Identification Number decoder (click the above image to enlarge) that Camaro5 managed to get its hands on, the 2014 Camaro might be getting ready to receive a few tweaks under the hood.

The biggest news is that an LS7 V8 engine looks to be joining the Camaro family for the 2014 model year. The 7.0-liter LS7 is currently used in the Corvette Z06 with a power rating of 505 hp and 470 pound-feet of torque, which is much less power than the supercharged 6.2-liter LSA V8 used in the Camaro ZL1 putting out 580 hp and 556 lb.-ft. Interestingly, though, there are no new trim level listed on the detailed sheet, suggesting this engine could be destined to find its way into one of the Camaro's existing model, though a few months ago, it was reported that GM filed trademark papers for the Z/28 moniker, a storied designation in Camaro history.

On the opposite end of the performance spectrum, the decoder also appears to indicate that the Camaro's base 3.6-liter V6 will become E85 capable. We'll wait until we hear official word from General Motors on either regard to get too excited, but both are promising leads for Camaro fans. Combined with this week's news that next-generation Camaro production will be shifting from Oshawa, Ontario to Lansing, MI, this has been a surprising eventful week for Chevy's ponycar.
