I currently own a 2002 F-150 with the 4.6 in it, I bought heads and intake off a lincoln mark VIII, I would like to know if there is any information out there to make this swap, what all do I need for electrical, so that it will match up with my current ECM. I am not in a big hurry to do it, the engine runs good now and handles everything I need it to do, but I would really like to make this swap, any info would be helpful.

 

you need more parts than what you have, you need the timing cover and related accessories, exhaust manifolds and a new exhaust mid pipe set up, you also need to tear your motor apart and replace the pistons with the higher compression ones unless you are going to be running boost at the 8.2-8.3 compression ratio you'll have after the swap, and if you're gonan be running boost the stock cast pistons are not a good choice anyway (feel free to ask me how I know )


you also need the wiring harness for the 32 valve or you're gonna have to modify your existing harness, plus you'll need the 32 valve COPS


your current ECM will need to be tuned for the better flowing heads and you need the 24# injectors at a minimum

 

well i can git a complete dohc 4.6 from mark 8 for around 600 bucks if that would be more simple also dose any one make a supercharger for the b style heads

 

you'll be better off with the complete motor if it's been maintained

 

and there's several centrufigals you can bolt on

 

ok in that case il just pull the sohc and save it for later how much my wiring harness is going to match up ?
