There's no replacement for displacement. 5.4 all the way if you've got the cash, then do an aluminum intake and 76mm garret. That'll work.
Yea I would imagine that would work quite nicely! Too bad I dont have enough money for all that...it would be a cheap build with a cast iron block but all forged internals...maybe get the heads reworked but other than that just a cheap build...thanks for the input!05102 said:There's no replacement for displacement. 5.4 all the way if you've got the cash, then do an aluminum intake and 76mm garret.

Thats what my goal is is around 400hp to the wheels...Is that with what I have now? I still plan on building another motor on the side that way ill have the stock motor still for collectors value if it ever gets to that point! Thanks!installermarc said:Problem with the 5.4 is it is a wider deck (between the heads) than the 4.6, so you need manifold adaptors, and I belive there may be a hood clearance issue with the stock intake. Why not spend a little coin on new heads (I'm looking at the new Trick Flow ones for the 2 valve), nice cams, and a tune. Maybe a little more than a 5.4, not sure. I haven't priced it out. But in theory, should be at 400 hp / 420 torques to the wheels.

Yeah I did see those 5.0 mod blocks too and that was gonna be my next option if I decided to stick with the 4.6! I think it would be neat to slap some 5.0 badges on the car and it have a purpose! I was also thinking of buying a complete engine outta a crown vic from a junk yard and just getting it machined then stroke it since the kits arent too bad...there are just too many decisions! haha Ill try to send a PM to the guy you mentioned and see what his suggestions are if I decide to go with the 5.4L! Thanks for the help!TXBLUOVAL said:Shawn you need to drop GBoger a line. He did a DOHC 5.4 swap in to his 2001 a little more than a year ago and he can tell you all about it. I think all he had to do was fab some simple plates around the mount areas but other than that the last I heard from him he wasnt experiencing any major problems. He installed an Eaton blower too, I think. The photos were very impressive, to say the least. Look him up here on IMBOC and drop him a PM. I'm sure he'll be quite helpful.
Another option is the new 5.0 MOD block from Ford Racing. They sell new for around $2-K and they have the same dimensions as the stock 4.6 in the 2001. There are also stroker packages available as I am told that will bump your CID significantly past the 5.0 size.
Thanks for the help guys! One question...what about the emissions? Im in NC and they have the emissions testing and all so will having the 5.4L kill my chances for passing inspection? Ive heard that some places will reprogram your computer but I dont know how accurate that is. And will the trick flow 2v for the 4.6L feed the 5.4L good enough? Thanks again!Bullitt 5.4 said:After a year of driving the 5.4, I have had zero issues. I am amazed at how tight the suspension and handling are still, even with the extra weight. Corners like it is on rails, get 27 mpg Hwy, and still run consistent 12s on street tires.
The only real issue with a 5.4 swap is the intake options. Adapter plates are not the greatest, but they will get you going quick.
I keep hoping that as the 5.4 swap gets more common, the aftermarket will respond with swap parts. A true 5.4 Bullitt intake would be awesome, just the way it should have been from the start.

Most stock Bullitts put down ~240 if I recall correctly.installermarc said:If your motor is close to stock (long block), without a blower, I would say close to 270 hp to the wheels. Mild bolt ons would push it closer to 300.
Ill do that! Gonna weigh all of my options and do some pricing and ill let you all know what I decide to do! Might be ordering a block in a couple weeks! Thanks!Mus408 said:The TFS 2V heads should work fine on a 5.4. Plus they will be coming out with two other versions of that head,that flow more! Give them a call.
Thanks man...Ill have to devote my life for the next couple weeks to read all the info in that thread! haha But im gonna get as much info as I can to help with my decision! Do you all think the t3650 can handle the extra power? And also my tri-ax is showing signs of needing to be replaced...should I get another or go with something else? Thanks again!!M1 Tanker said:Go to www.mustangboards.com
There is a HUGE thread over there. I would actually read towards the end as most questions have been asked and answered many of times. R3dn3ck has done a swap and is always helpful on answering questions. Spend a wek on reading the thread.

The 3650 has massive internals(huge gears,etc..)and the same gear centerline as the T56. The main issue is with the crappy syncros, Promotion sells an upgraded 3650 with a 26 spline input (and I believe carbon snyncros, need to check) that they rate for 750HP.BlackBullitt2615 said:Thanks man...Ill have to devote my life for the next couple weeks to read all the info in that thread! haha But im gonna get as much info as I can to help with my decision!
