The intake port is the diameter of a quarter (think paper towel tube) but 1.75 feet long. The head would have an enormous 375cc intake port. How do you think it would flow compared to a 227cc AFR head? You can compare minimum cross-sectional area. That is what matters. That is the pinch point that dictates a lot of the flow (not to mention the valve pinch point, lol) Having more valves is almost always a good thing.

That stuff I will agree with!

i know a 4 valve head cannot be compared directly. runner/port average cross section, length, taper, coefficient of flow. etc.

i havent weighed either one although i have played with the cast iron 05+ stuff a lot. i cut the 'collector' off of a 05 mustang gt driver's side manifold and the collector off of a 05 5.4 3v manifold and cast iron welded them back together for a manifold that allowed me to fit the 5.4 3v into my 96. 05 mustang gt manifold to 05 f-150 5.4 3v collector.

You're right about the old 5.0 though, I was thinking of some brodix heads.

the port specifics are in the 5.0 and super ford's february issue.

High Guys! Hope you dont mind a member from the opposite side of the tracks. I am not here to "Troll" or be a "Problem". I enjoy performance cars of all types.

What I have been told:
1. All models effected.
2. Seperate issues on each model.
3. (Statement of GM Employee) Not at liberty to disclose exact nature of the defects.
4. Shipping on hold until all cars have been inspected and repaired if needed.
5. Production is stopped for the week due to parts shortage.
6. Taking advantage of the downtime to fix the issues on effected cars.
7. New production will resume 4/26



I look forward to a few good natured grudge races with a few of you that frequent the Huntsville, Steele or Montgomery (Alabama) Strips. I hope the S197 5.0 vs the 5th Gen Camaro is as good a match-up as the S197 4.6 vs the 4th Gen LS1 has been.

First - WELCOME

Where you got my attention was when comparing the 4.6 to LS1s... Umm... unless you're talking about Terminators or something, and maybe even Mach 1 4.6s, there wasn't a good match-up to speak of. In fact, it seems it only ran from '03 to '04, like the Terminators. Having said that, I don't think there's a comparison to be made since they weren't produced while LS1 cars were produced. Symantics I suppose, but if we think about getting technical, there's no comparison in performance. Regardless, Cobra Rs, Terminators, and Mach 1s are/were pretty cool

03 Cobras were on the production line at the same time as the 02 Camaros. But yes it is semantics.

The car was given the model year 03 to extend sales. It was more like a 2002 1/2 Cobra when it came out.

And the crazy thing about them 03s is that from all indication they are still better, straight line, performers than the new Camaro and Mustang.

The car was given the model year 13 to extend sales. It was more like a 2002 1/2 Cobra when it came out.

See! We ALL can get along and learn from each other

have you seen what Roush has done with it? The 6.2 OHC from Ford can be stroked to 7.5Liters!

Roush has 7.0Liter versions right now making 800hp N/A!

N20 guys will love it as long as the rods and pistons hold up!

The NOS guys will hit the same limit as the FI guys. The Hypereutectic pistons will get explode happy at the first sign of detonation at those power levels.

I said this in the other thread but Whipple has already said they have a supercharger kit for the new 5.0 that makes 600hp @ 7psi on pump gas.

I saw that after I made the post you quoted crazy shit. And apparently the 2 valve, I think I read and remember they are 2 valve heads, flow some crazy numbers.

We are getting a little off topic here but I will respond to the no good match-up statement.

Im not talking about a competition in the market. Im talking about at the track. In my case its a pretty decent race if the LS1 is on street tires and stock to near stock. My S197 4.6 (Only Mods are CAI and Mailorder Tune) runs 12.8-13.3 at 103-107 depending on density altitude on factory Pirelli All-Seasons. I find the S197 60's better and the Camaro LS1 traps better. My better 60's make up for his 2 mph trap speed advantage most of the time.

I linked one of my slips in my sig. I chose it because I think I did a decent job on that pass and it is both an actual and corrected 12.
I used to get a lot of crap about how my better runs didnt count because of "Mineshaft Air".

I believe their is a comparison to be made as long as I and the other driver continue to line up in front of a Christmas Tree. Its about fun and who can put together the best pass right at that moment in time. That takes cars that are fairly evenly matched in performance not production date. I get no great thrill blowing off a TPI Camaro and Im sure LS3 Corvette Owners feel the same about my car.

PS Im not really a die hard Ford Guy. Ive owned both a Corvette C4 LT4 and a Corvette C5 LS1.

If those are the times you are getting for what you're saying was done to the car, then I'd say it would be a pretty close race. I'm still not on board with comparing mod'd cars to un-mod'd cars or cars that are not of the same vintage, but, really, what cars that go to the track really come 100% stock - pretty much none. I will say that it looks like you're a driver for sure

Like you said, though, let's get this train back on the rails Please keep us informed of new developments regarding the 'Stang. I keep my enemies close, if you know what I mean
