since the V10 is based off the 4.6L, it wouldn't be hard for aftermarket companies to create products for the V10. for headers, they'd just have to add one more pipe to each side. underdrive pulleys would be the same. forged internals the same except the crank. throttle bodies are standard Ford issue. cams wouldn't be hard to make. the only problem aftermarket companies would have is heads. and we have that problem now with our V8's that have been out since 96 in the Mustang.
awalbert88: 351ci = 5.8L
SVTdriver: the V10 weighs less than the 03 Cobra motor, so handling would actually be better. crash tests should not be a problem as the frame is designed to take the brunt of the impact and not the engine.
Uh.. I'm well aware of the fact that 351ci is 5.8L. I have no idea what you were replying to by telling me this....
Making headers for a V10 is not necessarily as simple as adding a pipe to each V8 header. Heads are a lot tougher to do (not that there's much of an aftermarket to build off of with regards to heads for the MOD motors anyway...) Cams aren't hard to make, but would still be more expensive for the V10, because it's a longer, more complex motor.
Crash testing is required every time you put a different motor in a vehicle for production, because it changes the weight balance. Yes, the V10 may be lighter than the 03 Cobra motor, but it's longer, so the weight is distributed differently. Having seen firsthand what happens to the front of a Mustang when it sustains a strong front impact, I can asure you that the frame is not the only thing taking a beating. The hood will compress down and in; the bumper covers will fold up (or down, depending on the type of impact), and the radiator will easily be bent in or punctured from the running horse/snake emblem being pushed in. Now, the motor might be untouched, but more than likely the hood will push against it, stressing or damaging front accesories/pullies, and the same for the radiator compression.
Now I can't say how an 05 Mustang will do, but I suspect many of these same things would happen. Keep in mind that my notes above are based on a 20-25mph impact with a telephone pole. Anything faster and the frame will almost certainly bend, rendering the car effectively worthless. Once that happens, the motor will start to obsorb a lot of impact, and slam into the firewall. With the V6 or even the 4.6 V8, there's still a good bit of room for the motor to move in the event of a severe impact. You don't want it to smack into the firewall that easily, because it could puncture it, causing the car to fail collision testing.
Again, I don't know how the 05 would do, because I've yet to see under the hood of the final production version.
