As I understand it there is a HP increase in the 5.7 and 6.1. I believe I read it on Charger Forums and I'm not too sure how accurate the info was. But I believe the power will be increased for the Challenger, If I was a betting man I would bet that it will be. And yes, the Camaro is the competition for the Challenger. The Mustang... nice car but not a race horse by any means. For the Ford crowd, I hope they increase the HP. They have a long way to go to catch the LS2 and 6.1. GM is holding their cards for now and won't show their hand. But if they do have more ponies, my next call after getting the Challenger will be Mopar Performance. I love to suprise people. And before someone says that the Camaro comes out in 2009, I know... it looks like my Challenger will be 2009. Good luck Mustang and good luck Camaro... if you run into my Challenger it ain't stock. It will look stock, but I don't own 1 car that has not been modded.
