The intake is already optimized, but I suppose there are a few horses that can be gained from either a ram-air intake or a "CAI". Ported heads? sure..more aggressive cams (since its a DOHC)..sure..but I'm not sure there is a great deal of N/A power left on the table out of the new 5.0. It will be more difficult to mod than the 5.7L Hemi..and will likely produce less power on a HP per dollar basis.

Put shorty headers, high flow or no cat mid-pipes, a tune and cat back exhaust on a 345 Hemi? you've just picked up 35 RWHP Add in ported heads, a new air intake and a new cam? you've got ~85 RWHP over stock Mind you the 5.7 Hemi is a difficult engine to work on, but has tremendous potential in it.

The LS3 and L99 motors are powerful motors and are FAR easier to work on than the Hemi's (history is repeating itself, yes?) and respond to mods very very well. The LS3 and L99 respond so well to simple mods its a beautiful sight to behold.

Make no mistake..the 5.0 is going to be a very fast motor and the 11' GT is going to be a runner in the 0-60 and 1/4...but it doesnt have the mod potential that the Hemi's do (5.7, 6.1 and 6.4) or the ease of modifications like the LS3's and L99's do.

Ford's brought back the 5.0..and pushed it damn near to its limit, there is only so much you can do on a 5 liter engine while keeping to traditional push rod technology.
