1996 Non-PI to 2001-2003 PI engine swap

I am looking for information on swapping my 1996 GT 4.6L with Manual transmission motor for a used low mileage 2001-2003 Mustang GT 4.6L engine. Are there any difficulties to doing this swap? Any difficulties bolting my coil packs on the new motor? will all my accesorries transfer over? Do i have to worry about the motor coming from an Automatic and my computer or harness not working? Might change the cams to a slightly better grind, any suggestion on cams (good torque and HP w/o redlining it to achive the gains)?

You can look at the PI swap write-up that is in the stickies for info, and also use the search function.
This question pops up almost every day on this forum, so there is a ton of information available about it.

Sticky

Sticky is for the PI swap (heads and intake) i am wanting to swap the complete engine. I have read through roughly 100 or so threads and have a good idea but some say it will not work if the replacement engine came from an automatic and it is going into a manual. Prefer not to do the "PI-swap" unless i can not do the complete engine swap or find a low mileage 2001-2003 replacement engine for under $1,000.

I just recently completed my complete PI engine swap into my 96 GT; there are a few things that will need to be swapped over like the timing chain cover from your old motor to your new one, you'll need to run your old fuel rails with your new motor, I used my old fuel injectors as well as my computer was set-up to run with my old ones, obviously you'll have to swap over the coil packs, and I'm drawing a blank for right now I'll take a look at my stang and see if I can remember what else we did if anything. Good luck on the swap it's well worth the time.

who ever said the bell houseing is diffrent between the auto and manual was not very smart. the motor is the same they do not change for auto tranny's or manual.. it should be a direct swap the motors are the same just the heads are diffrent and manifold. you will actually get more power useing ur non pi motor though and just doing a pi swap.

cams, and all basic bolt ons, arizen seats, cowl hood, and now my buckets got a hole in it (meaning im broke) but when i fix it ill have gears and some trany work

I think the automatic transmission post was talking about a possible problem with wiring harness.
