Madmerc said alot of things wrong but his point about modular vs pushrod engines is valid in at least one way. Compare NA modular applications with those of the current pushrod competition:
Chevy Small block
LS2 6.0 400 HP - 66.6 HP/Liter
Ls7 7.0 505 HP - 72.14 HP/Liter
DCX Hemi
Hemi 5.7 340 HP - 59.64 HP/Liter
Hemi 6.1 425 HP - 69.67 HP/Liter
Ford NA Modular
4.6 SOHC 300 HP - 65.21 HP/Liter
4.6 DOHC 320 HP - 69.56 HP/Liter
5.4 SOHC 300 HP - 55.5 HP/Liter
5.4 DOHC 385 HP - 71.29 HP/Liter
So isn't the point of an OHC engine to make more power with less displacement? Except for the Cobra R engine the NA Modulars make LESS specific output than the pushrod engines! I hope that's not Ford's idea of "built for the road ahead".
There is however a glimmer of Hope in the 5.0 Cammer engine:
5.0 DOHC 420 HP - 84 HP/Liter
I hope Ford takes the rest of the modulars in a similar direction. Bore the 5.4 out to 6.0L so it can make 400+ horsepower. Or decide to actually produce the 427 Hurricane V8
