The next-generation Chevrolet Camaro Z28 won’t arrive until 2011 – some time after the convertible Camaro makes its debut. That will give the 2010 Ford Shelby GT500 some time to eat up some of the high-performance muscle car segment. However, if you can’t wait until ‘some time after 2011,’ Hennessey is offering its HPE550 performance package for the Camaro that takes output up to 562-hp (the Camaro Z28 is rumored to get the 556-hp 6.2L LSA V8 supercharged engine from the Cadillac CTS-V).

The folks at Inside Line happened to have the new 2010 Shelby GT500 and Hennessey’s HPE550 on hand at the same time and decided to put the two high-performance muscle cars head-to-head.

You can check out a video of their test after the jump.
