I dunno man, at 3.6 liters, 304 hp NA is pretty dang good. Seems it's already been 'tuned' from the factory to scream at near its best. I'd be surprised if you could get 340 out of it with bolt ons (headers, exhaust, intake, computer tune). I mean, the little guy's already got DI and over 11:1 CR! He's already overworked! (but doing a fine job of it!
) Another thing that I like to conveniently overlook is the 3.6's torque rating of 270 foot pounds. It's good, yes. But I'd like to see mods that bumped IT up into the 300s too. As cool as it is to say to a mustang GT owner "I have more hp than you," he can retort quite handily "Ah, but I have a substantial excess in torque. And I weigh less. "
