3 valve head info

[2k5 pony]

Just joining the forum and like everyone else is frantically waiting any new news on the 05 stang. I ordered a mineral gray 5 speed on 08/21 and can't wait...anyways here is a link to a bench flow test on the 3 valve head from 5.0 mag. I was to glad to see any good news on it since that article on BON.
You guys have a great forum and I'm looking foward to hearing news from the members who will be receiving their new stangs soon

Thanks for the link 2k5pony, a great article!
Real #'s not speculation! That's what I like.

Rather than one 1.76-inch intake and one 1.41-inch exhaust valve like its '99 PI predecessor, the new Three-Valve head (bottom) features two 33.8mm (1.32-inch) intake valves and a single 37.5mm (1.47-inch) exhaust valve. According to Ford, the use of twin intake valves not only improves engine breathing, but it also improves the mixture of air and fuel prior to combustion

I like this too:

Jon is really excited about the raised intake and exhaust ports. He says there is more potential to be found in these heads,

Those exhuast ports remind me of the Cleveland exhaust ports.


And for the person who thought I was blowing smoke when I said the 05 Stang GT and F-150 5.4 used the same heads:

And when we say the 4.6 '05 Mustang and the 5.4 '04 F-150 share the same cylinder head, we mean the same cylinder head, right down to the camshaft and the part number

Or how about this quote:

Carls says these heads should easily support high-300 to low-400 hp at the wheels with the right bolt-ons

And the all important intake flow #'s (all stock @ 0.500 valve lift):

99 Cobra 4V: 248 cfm
99 GT 2V: 179
05 GT 3V: 235

So the '05 3V intake flows only 5% less than the 99 Cobra 4V and 31% better than the 2V PI head!

Thanks for thr link! I'm excited to see what's going to happen once all the tuners get a hold of these new 'Stangs. Considering they have the cool 3 valve heads and VCT, I would think they should have more tuning options than before.
