if it's going to be a 5.4L, i doubt it will be a 4V with a lysolm s/c on it. that would be the same engine as the Ford GT. i just don't see it happening. 3V with the eaton roots, maybe. but even then, that's a heavy engine for a car that is supposed to compete with a current Z06 much less one with an extra 85+hp and a few less lbs. the 5.8L V10 may be a better choice for Ford. it would be less expensive and lighter while still producing 500hp.
I thought the same thing. I was told that this is the motor currently in the mules and is thought to be the motor of choice for GT/Lightning/Cobra. I'm sure they'll play with the ratings to not have a $40K Cobra outpower the GT though. We'll have to wait and see.
