As some of you know a 5.4L Triton engine can be swapped for a 4.6, but how about a 6.8L V10? From the research that I've done it's basically a 5.4 with two extra cylinders, so the height and width shouldn't be an issue since the 5.4 has been successfully swapped. I found a website that has the specs of all of the modular engines, I realize that the information could be wrong like anything on the internet, but the 6.8 should fit if it is correct.

The website says that the 6.8 is 3.5 inches longer than the 4.6 and when I measured my 2005 GT I had a 4 inch gap between the belts on the engine and the fan. Now the 6.8 is 140lbs heavier than the 4.6 according to Sullivan Performance's site, would that make the car to front heavy even if someone was able to get new front springs and adjustable dampers to account for the extra weight? From the things I've read about the 5.4 swaps a custom intake manifold and exhaust headers must be made since the heads are 1 inch higher, would this still be possible on the 6.8? Also some people say that you would have to swap out the ECU, but if you have a 4.6 3V and swapped a 3V 5.4 or 6.8 would you still need to swap the ECU? This is still confusing to me because some people say yes and others say no.
Am I missing anything? If this is actually feasible I would definitely consider doing this swap after I graduate college. How much would the intake manifold and exhaust headers cost? I realize it might end up being the same price as a supercharger, but I would rather have a mustang that is completely different than another mustang with a supercharger.
