thank you for the info. i've already performed the hybrid ign mod(which was performed when the carbed engine was in, (it was GREAT) 5 lug conversion, put in a 5.0 HO with the the injection system, including the tank, put in a 93 dash, console, 3g upgrade, mini starter, etc, etc, now i want a 4.6 with auto trans. i always try to keep the swap as close to stock as poss, cheap and reliable. i was lucky to find a smashed 97 with a 4.6. i think the k-member is ok,the guy also Gave me a smashed running 95 v6 mustang with 60k the as he wasnt sure the 97 member was ok, or if the k-members would interchange. i also want to use the hydro boost, speed control, a/c, tank, radiator and cooling fan, air filter, pcm, wiring loom, etc. now that i have the 97, i can have rear discs brakes!!!, i also have an intact 2004 grand marquis eng with 30k with a blown bottom-end due to no oil. i will do the head upgrade later. sorry to ask a lot of questions, but i have never done the 4.6 upgrade before. it seems a lot of work,
but i am looking forward to doing it, and i'm fortunate enough to have an intact donor for parts. i just want everything bone stock for reliability & financial reasons. i dont se any horsepower gains at the moment, but i just want a change.
