this makes no sense. lol I would call the service department. ask to talk to someone working on your car, and ask them exactly what engine they are putting in your car. I swear, dealerships are morons, 9 out of 10 times.
all hell would break loose if they put a 288hp motor into my Camaro.
edit: if they are somehow able to put the lfx in your car, that would be pretty sweet.
