Well...I don't think a 5.4 liter motor with those GT heads/cam is going to be making anything under ~450rwhp.

Supposedly, a pre-production car dyno'd 489rwhp a few months ago.
Link. Scroll down to post #89.

I'd agree about the weight, if it's accurate. Personally, I don't think they're going to weigh the 3900lbs. everybody is throwing around. I'd guess they'll weigh in around 37-and change.

I saw the new motor trend and it reads the gt500 runs 11.6 @ 128mph on radials... BS, a 3900lb car running 11.6 and is rated a 475fwhp... nope

Agree 100%. Don't know what orifice they pulled those numbers out of.

My guess would be 12.7 @ 112... just my .02

I think it should pull alittle better then that since lots of the 03/04s pull that. You know the 5.4 with that blower will have more torque then the 4.6 and it will also probably be underrated to..... IMO

IMO, it'll be quite a bit quicker than that.
I'd bet low-12's or high-11's and trapping around 116-118mph.
