Having a 4.0 and 4.6 and talking to a couple diffenent mechanics I can add that the 6 is much more reliable than the V8. My own experience I've had coil problems(which the 4.0 doesn't have) and am still working on a #7 misfire problem that I haven't quite figured out yet plus plugs are known to shoot out of the 4.6 so from a reliability standpoint the V6 wins.
That's a new edge problem, not the S197. The S197 Gt's have their own Spark plug issues as in cementing themselves into the head from carbon build-up and breaking apart when being removed after 50K+ miles thanks to the 2 piece design of the plugs.
As for performance differences between a S197 V6 and GT remember that the computers in both cars are adaptive. So to drive a broken in V6 vs an off-the-showroom GT is no comparison. I bought an 08 GT auto with 82 miles on the odo and I can tell you the car has woken up since I've broken it in (1300 miles now).
Times for the both manual and auto GT are nearly identical in the 0-60mph and 1/4 mile with the manual having a slight one or two mph advantage at the trap. Auto's can be slap-shifted and it makes a HUGE difference in acceleration as does making sure to have your TCS off. It's factory on the GT, not sure about the V6. The TCS in the GT is seamless. I tried to spin the tires with the TCS on only got a slight slip, not even a chirp. Turned it off and good god I couldn't get off the gas fast enough to keep it from roasting the tires and had to feather it when it shifted to second to get the grip back.
I came from a V6 manual tranny (00) so I do occassionaly miss teh stick but I won't back to manual. I can actually channel surf on the radio now when cruising to work in rush hour traffic.

We sixers have german made engines. Assembled in America. Gt's on the other hand have american engines but assembled in mexico. My dad and I test drove the GT a month ago and there is a huge difference. I love both cars, test driving the Gt was sooooooooo fun but an extra 5-8 grand plus double the insurance isnt worth it. Someday I hope to buy a GT myself =)

the 6 cyl engine is made in a ford plant in Germany. the 8 cyl engine is made in Michigan. the MT is made in Mexico, and the AT is made in France. i believe they are both assembled in Michigan at the ford/mazda plant.
It's the manual trans. It bakes a HUGE difference in our cars. I have a manual sixxer. I think it's plenty fast. I got a chance to drive a stock auto GT. I was not super impressed. I truly feel that with a fair amount of go fast parts and a tune, I might be able to take a stock auto GT. On the other hand, Those manual GT's are pretty quick. If they have some go fast parts and a tune, They are probably beasts. Although, you don't see a lot of GT's modding thier rides.
On cold days my v6 manual which is stock except for ninosport duals actually seems to get 0-60 times closer to 6 flat or at least very low 6s.
onederful100, that was a good read. I'm curious as to what other vehicles around the world use the 4.0L. Also I thought Tremec(who makes the transmission/manuel) was a Canadian company. Wouldn't make sense for them to make them in Mexico I wouldn't think.
I know I had to be off a little bit but I usually do this for fun in the country with my friend. We get a stop watch and manually clock the 0-60 and I have gotten in in the 5's with my automatic tuned pony with parelli's. I admit though, some days it really does feel like it pulls WAYYYYyy harder than usual. I haven't even put in my 4.10's yet either.
I was driving to work yesterday morning and had to pass about 2 farm trucks. I floored it right after a stop sign (it's in the country) to pass them quickly before we got back out into traffic ahead. It just SCREAMED through the gears. I could see some people in the distance that were working on some canals turn around and stare when I passed. It just had soo much extra today. It was a bit chilly out. My mustang is n/a but not stock.
I test drove an automatic GT and can tell you that there is a considerable difference between that of the stock automatic GT, a tuned automatic GT (HAULS!), and a stock manual GT (regardless of tune really). My favorite of those was the manual which you could really tell that it had some power behind it. The auto GT without the tune just felt... like oatmeal... with getting up and going.

I would love to get a GT. I haven't had a chance to check out the power difference.....yet. I live right by the Ford plant where they are made. Most of the Mustangs around here are V6's. Very rarely I see a GT.
Yesterday after leaving my sisters, me in my car, hubby in his Dodge Ram. I pull up to the light next to him...he jumps his truck, like to say let's get it.... I smile, and say let's go. Light changes and I let it scream off the starting line...lol I had him by a couple of car lengths real quick....I'm pretty sure he let me win...but fun none the less.
I had a chance to drive a shelby mustang. I dunno they just felt heavy to me. My 6 felt alot quicker, even tho it was supercharged and all, but still. The shelby gt felt big and bulky to me.

Introducing......Christine (Sha-ney-ney)!! My New Baby!!!
About 6 months ago, I went to the Ford dealer "thinking" of trading in my V6 for a new 2008 GT. The dealer wanted to give me $13K for my car and sell the 2008 Candy Apple Red GT Manual for $27K. I thought it through, we wrote down numbers and did some math. I really wanted to get an idea. So...finally, we went to take it out for a test drive. I took it out on a back road which was perfect. He said at the stop sign, floor it. So I took the offer and did so. Unfortunately, the only thing that really impressed me was the V8 growl as I took off and the impressive shifting through gears compared to my T-5 manual tranny in the V6. I was REALLY disappointed. I expected to be blown away. Expecting to be immediately convinced into buying it. The dealer said "Fast huh?". I said "Yeah." That's all I had to say. Of course, we got back and I said I think I'll keep my stang until Ford releases a more impressive GT that really separates itself from the performance of the V6. I think they put the two cars to close in comparison this time. So hoping for 2010, they will blow me away
Well there are more impressive V8 S197s but they all cost a small fortune. There's even a 5.0L special edition Parnelli Jones I wouldn't mind owning, but I think that one was still the SOHC engine. I was really hoping that Ford would put out the DOHC 5.0 but maybe that one doesn't get good fuel economy at all, who knows.
what would be the advantage of DOHC over the SOHC...i was under the impression that saying a DOHC was better than a SOHC was like saying a 32V is better than a 24V

i assume the same thing. more valves, more power potential.

Sounds like you left the Traction Control 'On' IMO. it's on by default when you start the car. It kills the acceleration on the GT's. Eitherway, A brand new S197 dogs (V6 or V8). You need to drive one that's been broken in.

here is what i knew i had read somewhere on this topic. a quote from the other forum:
"I think the factory heads flow pretty decently, and flow very well with a good port/valve job. Who cares how many cams are there? Sounds like ricer talk to me ;)
'I have 16 valves too!' C5-driving friend of mine to a Honda boy."
lol just thought i'd share that

lol....good point. i guess there are many variables to everything auto related.
