5.4 4v VS 4.6 4v

p4ndiamond · November 25th, 2011, 11:22 PM

Im going pick up a 5.4 4v tomorrow from a navigator. just wondering what complications are had for swaping in this motor to my car. im on an auto trans also. I will be rebuilding most of the motor . i can get either one for 194 bucks...just wondering what one i should get and if the 5.4l 4v will even fit.

Thinking of the cobra R i figured it would since its an sn95 body under the hood basically. Where can i find the thread on this, thanks. So excited

-You'll need adapters to make the cobra and mach intakes work
-long tubes aren't available
-the a/c line the strut tower has to be relocated
-the k member has to be spaced doen 12mm to allow for clearance at the master cylinder
-a 4.6 coolant crossover will have to be modified to fit

Where do you live?

Nice man i just drove mine for the first time today! And i love that 4v!

p4ndiamond · November 26th, 2011, 12:24 AM

The k member did it in for me. the 4.6 4v it is then lol. and im located in Louisiana both north and south. New orleans (in the city itself)
And in ruston by La tech university.

p4ndiamond · November 26th, 2011, 01:49 AM

so i have not heard of the K member lowering by 12mm anywhere else. what is the purpose of this . had not read of any clearance issues with it.

im still jealous of you 4v guys....ugh...i want one so bad but i keep sticking money into this engine..once again it sucks living where i do, seems no1 is into the same things..everyone in this area wants to be jerseyshore and go to the bars..pfff lame

p4ndiamond · November 26th, 2011, 08:54 AM

lol i was helping a friend and found these motors . im in an area where no one cares about these so they just sit there all day . the turn of events leading me to this are pure luck. im stoked

A 5.4 4y motor would be totally sick but would cost a fortune to build up if you ever wanted too.

I personally would go with the drop in 4.6 4 valve.

p4ndiamond · November 26th, 2011, 06:29 PM

Yeah already picking out the 4.6 DOHC....umm its not comming out ....everything is disconnected but something is still holding the motor from the back. its the 1997 Mark VIII of course. Any ideas. gonna give it another try in the AM

OptionalStang · November 26th, 2011, 07:28 PM

ya the junkyards around here are full of every 4.6 you can think of...i even found one with a cobra engine, had slight damage but easly fixable.

I imagine you need some "antifreeze" as cold as it gets up there.

MustGT98allday · November 27th, 2011, 02:44 PM

i wish their were 4v's in my local junkyards!

p4ndiamond · November 27th, 2011, 06:26 PM

Nice when i pulled mine i payed 250. Then got a 120 back for core return so essentially i payed 130 for all of it. Harness everything a 50% off day@ normally the engines are 500 if they had less then 100k miles.

p4ndiamond · November 27th, 2011, 09:32 PM

Nicee. im gonna rebuild the sht outta this engine lol.
pics or it never happen. pulled it from the top too. it was actually rather easy. (sarcasm alert)
