Let’s be blunt for a moment here, and say that we were seriously disappointed with GM’s choice to offer almost nothing in the way of options for the 2014 Chevy SS. Not even a manual transmission option? While that will be remedied down the road, as it stands Chevy SS buyers have a very limited color palette and option list to play with… at least from GM.

If you’re willing to look beyond the dealer lots though, you’ll find plenty of options to boost the performance of your Chevy SS, especially if you look to Hennessey Performance Engineering. HPE has announced a wide variety of performance-enhancing packages for the Chevy SS, offering up to 1,000 horsepower in the super sedan. Can’t complain about that.

Starting with the HPE475 package, which adds enough modifications to boost output to a respectable 475 horsepower, the kits grow in complexity and cost from the HPE550 all the way up to the top-level HPE1000 option. This all-out performance package completely removes the stock LS3 in favor of a twin-turbocharged 7.0 liter LSx engine rated at, you guessed it, 1,000 horsepower.

Remember how we were complaining about the lack of a manual transmission? HPE solves this by offering buyers the option of either a beefed up six-speed manual, or a stronger six-speed auto. If you’re going to invest in a car like this though, with all that horsepower, the automatic might be the way to go. Then again, shifting for yourself still has that old school appeal. Which way would you want to change gears in your 1,000 horsepower Chevy SS sedan?
