Power is always there? Obviously they haven't driven an EB for much time.

The Torque peak on the EB is higher and sooner than the 5.0. There is almost Zero Turbo Lag with this motor. Read the article above, it frames it Very nicely.
Don't get me wrong, the Coyote V8 is a GREAT motor, but the 3.5EB just works REALLY well in these Expy's. Not to mention, a little tuning and they become downright fun. My Edge with the 2.7, and a 93 Agressive tune can embarrass sports cars 2 and 3 times it's price.
I polled my local tech's and the majority said that you can't go wrong with either engine, but if you want power, go EB. They did say the 5.0 sounds GREAT, and it does. I didn't buy cars for the exhaust sound, it helps, but for the go. These EB's GO!
