Seeing a nice mustang is like seeing a beautiful woman. You walk up to the car and lift the hood and there lays a v6. It's like taking that chick home and pulling her panties down only to find out she has a dick. Most guys don't like that but I guess some of you do.
You think? Hardly... for me the fun part is when the V8 catches up to me, and sees under my hood, that "Oh crap I was schooled by a V6" look is worth every dime I've invested. But then again, I hate seeing the same old crap all the time and am always looking for something new and unique.

And I love that 4th grade "you're gay b/c you own a V6" slant. Nice. Impressive. Really solidifies that reputation the V8 crowd has. And if "EVERYONE" hates the sixer Stang, why to they outsell the GT and Cobra combined? By the way, the definition of the "pony car" is a sporty affordable car for the general public to enjoy on the streets. Again, knowing history of what you are driving is a plus.

at times like this i wish i hada supercharged v6. It always comes out to be a v8 is better than v6 argument whenever anyone has questions on a v6 motor. Lilroush i applaud you for having the smarts,the car, and the ability to put up with all the bashing over and over again

I love the fact that none of the V8 boys can tech talk their way out of why they think the V8 is better.... because so few of them have even driven a V6, let alone understand how to build them, what they can handle or what it really takes to step up the performance.

I used to be one of those guys. In fact, in all honesty, I bought this sixer for a fuel sipper since I was driving an 11 sec fox at the time. Considered the 4 cam swap, but so many Mustang friends gave me crap for driving a V6 Roush that I finally said 'screw it', and decided to look into modding it to the point it would run laps faster than theirs. Turns out Ford's 3.8L/4.2L responds better to mods than my pushrod V8s where doing, and for a lot less money (buying six of a part is cheaper than buying 8 of them). The 4.0L motor has a lot of backing from the truck line, so many methods are proven already. These stock 3.8L blocks are amazing. We've yet to crack one from too much power - and they're taking 900 flyhweel hp plus with little more than a forged bottom end and gridle, ported factory heads, cam/ valve train, fuel system and boost. Better intake plenum design flows air very well, stock heads work great just being ported... the list goes on.

The v6 makes much less power per liter of displacement than the v8 last I checked.

The v8 is the superior engine, it has variable valve timing, an intake manifold that wasn't made to resemble a drinking straw, a dual throttle body, 3 valves per cylinder instead of two.

In contrasting the v6 and v8 you see that the v8 has revolutionary new technology, on the other hand the v6 uses antiquated technology, it's such a bad engine that it needs a shaft in the middle of it to rotate the cams the right direction because in the year it was made they hadn't figured out a better way of doing it.

This engine is so unimaginably antiquated that it predates the existence of the Mustang itself by a few months. So unless progress has gone absolutely nowhere you can rest assured the v8 is the one to pick if you have to choose.

Wow, that all sounds so well written, but you also like to offer all sorts of wrong info in the Roush/Saleen section in that same matter.

Power per liter... in stock trim, sure. Modded? Hardly. We're talking about modded cars, not standing in amazement that a larger more expensive motor makes more power. That's not really ground breaking news.

Again, here comes NO FACTS, just fancy talk to make it sound good.

And just for clarification, are you saying the fuel injected SOHC 4.0L V6 motor was around in the early 60's? You do state it predates the Mustang itself. Please explain.

Right such as me saying that Saleen is both faster accelerating and better handling than Roush. As I remember you fell out of your chair over that.

The fact is that they put two professional racing drivers in the Saleen and Roush Mustangs and the Saleen was chosen by far by the professional driver in for it's handling.

Also the P-51 Roush doesn't compare to the S302E. The E accelerates much much faster.

I said Saleen was better because it's quantitatively better in lap times and quarter mile times.

Per dollar I don't think the v6 makes sense either. You can slap on a $4500 Eldebrock supercharger and make 530 hp on the v8.

For $5000 with an STS Turbo running the same boost on the v6, with a more expensive installation, with a worse power band, for more parts cost, you get 27% less horsepower and 15% less horsepower per liter.

You wanted facts those are facts.

Obviously the engine was upgraded to fuel injection and some equipment like the alternator was moved around but what the v6 is some part an untouched relic.

A heavily modded v6 will never beat a heavily modded v8. That probably doesn't make sense to you though.

It's so cool to dump big money into a v6 just so you can outrun these stock or slightly modded gt's. You know I think I may try that. Sounds like fun.

My opinion is that yes the GT is a higher caliber platform to start with; however, the cologne 4.0 liter engine and mustang platform is reminicent of the cosworth v6 in the older model capris.

Some of the v6 cosworth capris were classics. OKay so a mustang is not a capri and the cologne is not running a cosworth top end, but like the cosworth, it is a cologne engine with an overhead cam. I love the old mustangs and capris. When I found out that cologne was going in the new mustang with overhead cam, I thought it was pretty damn cool. Okay so its not as cool as a v8, but you can't sit there and tell me that it is not true to the way of ford because the capri/mustang were almost identical platforms and both awsome cars with a v8 or a cologne v6.

As far as which one to mod, it depends upon what goal you set and your budget. The bottom line is that the v8 has more potential. If your goal is to have a reliable car over 400 horsepower, stick with the v8.
