The problem is that everyone is agreeing with Gearbanger. EVERYONE here has acknowledged that the Coyote is far superior to pretty much any motor previously put in a Mustang, especially a 2 valve. YES, the 5.0 is a far more efficient motor. YES, the 5.0 is much stronger in stock form than a 2 valve 4.6. YES, the car that motor goes in is much more refined, better handling, more comfortable car. YES, it comes with a nice warranty. We all agree with those points. No one here is debating any of that.
The only point that BurningRubber and Tank_567 is making is that it would be much more cost efficient to build and boost an existing 4.6 motor than swap in a new 5.0 and boost it. The price of $17,000 has come up several times as a minimum cost it would take to swap in 5.0 and boost it to the level of around 600 rwhp. (I would prefer getting the entire new car, but that would be $30,000+ and even further illustrate our point). For $17k, you can build one hellacious 2 valve. Here, I'll break it down. I'm leaving drivetrain and labor out of it because I'm assuming it would be about the same for either.
MMR1000 5.0 stroker with all the goodies: $4000
Ported and polished (by MMR) Trickflow heads: $3000
Custom cams and required upgrades: $1000
Intake and required upgrades: $1000
Big turbo or Procharger: $6000
That totals a very liberal $15000, which leaves $2000 for miscellaneous stuff and a tune. I'm not particularly knowledgeable in terms of big horsepower builds, but I suspect that setup would make 800+ rwhp with plenty of room for more. A 600 rwhp Coyote would not stand a snowball's chance in hell of keeping up with this motor in terms of power.
I am not saying that this motor will be more fuel efficient than a 5.0. I am not saying that this motor would be comparable for daily driving. I do not care that we are comparing a built motor to a stock motor. All I am saying (and BurningRubber and tank_567) is that, dollar for dollar, you can build a faster 2 valve motor much more powerful than you can buy a new 5.0 and boost it.
Now do not misunderstand me, Gearbanger. I know how much technical knowledge you have and how well you can get it across, and for that I must give you the utmost respect. I agree with about 99% of your points on any topic, including this one. The new 5.0 is the best motor and the best car that Ford has ever built. But to suggest that I can't build and boost a 2 valve to make more power for the same $17k it would cost to swap in a stock 5.0 and put a base model blower on it is just silly. That's the only point any of us here are making.
Now, thats funny no matter who ya' are.
