I think it's 240hp at the crank and about 210 to the wheels for the sixer. And 300 or about 265+ to the wheels on a GT. Any place like edmonds.com. Just type in 08 mustang specs on google. You'll see a ton of places. :bigthumbsup
although it's rated at 210, a lot of experts think it's actually more. They say that because the RWH should be less that 180. I have read threads in here where they have dyno'd our 4.0 after installing true duals and CAI with tuner and measured 200+ at the wheels. That's really pretty good for no internal mods. If I'm not mistaken, it's what the previous GT version put out.
To give some perspective, the 94 GT was rated at 215 HP 285 TQ.
The 4.0 is pretty decent for what it is. I am a V8 guy and and the V6 impresses me. Its not going to kill much on the dragstrip but for a daily driver its a blast. Especially with a manual tranny.
