Don't want to high jack, but do you wanna copy me too fryr? Or start a discussion post in the Auto section. As for your alternator, you may get close enough finding an Infiniti model that will bolt in, my guess is that they would be significantly larger and probably okay and better at idle. Not sure on the rice burners, but Lincolns definetely come with a bigger version than their Ford counterpart. Worth looking into, but I know nothing of the new Infinities. Loved the first Q45's though, just unbelievably expensive to fix. I'll see if I can get a little write-up going with my limited knowledge. As far as the Infinty stuff is concerned, The unit he has now will be the ONLY drop-in replacement, ie no modification necessary. With modification you could in essence make any alt work as long as the regulator functioned just as the stock one. Refulators are weird: they can look the same or have the same terminals, yet be electrically different in the functions. As for the Ford's, since the they have 6 "generations" of alts (1G, 2G, 3G, 4G, 5G,6G) and will have a small and large case for each. The smaller one is generally a lower output. For instance, my Taurus and Cobra use a 3G-130 amp unit, while it's ounterpart is the 3G-95 amp unit. The 95 amper will have a slightly smaller case, something not too distinguishable unless you have them next to each other. If you really want to get confused, have a dabble at Delcos. They have such minor differences that are often impossible to catch without years of experience working on them. I am always grabbing an incorrent end-frame. Ticks me off.
