Engine blew in my 2000 GT so I decided to go with a 5.4. I have flat tops which should put me around 11.1, a set of comp cams and pocket ported heads. Not sure what it will do power wise, but I think it will be a fun daily driver. Have no intention of being the fastest, just wanted a fun tire shreader!
Let me know what you think. (wish i would have started taking pics sooner)

The bottom 2 are videos of the engine on the sim test machine @ the shop.
Hope this wasnt too many pics...more to come!
 
Looks nice. I think a 5.4 with that much compression, heads and cams should get you in the neighborhood of 400 hp, maybe more. The torque is gonna be serious. I don't see any intake spacers, what intake did you use...??
 
Thanks for all the comments...except the one about the mechanic.. that hurts..lol I did use the professional products spacers and intake. I just painted them black to try to conseal them some.
 
what are you using for headers? I have always wondered if someone made headers for this kind of app.


I am using stock manifolds for now..I may end up putting shorties on it later. I have heard there is a company that makes longtubes for the 5.4 but there was no way I was going to fight those things. There is no room left with that thing and I am not sure if 4.6 tuned headers would fit. I had to trim the passengers side manifold to clear the inner fenders.
 
planing the same swap in my 97 , awesome progress your making , using plates with the PI intake ? keep us posted.

Yeah It has the professional products adaptor plates and professional products intake. Thanks for the comment. I should be getting it back from the tuner in the next few days. Ill try to get a dyno vid to share with you guys.

I tried using BBK equal length shorty headers when I did my 5.4 conversion but it was rubbing the fender well so I used the stock exhaust manifolds. There is a company that makes a set of headers specifically for this swap (I think it's Kooks but not sure) but they cost like $700+ so I don't know if it's worth it. The Ford Racing short tube headers should fit, and they are better than the stock manifolds. Are you gonna delete the EGR valve...?? What X-Pipe are you gonna use...??
 
I think it's cool when people do the non-traditional things like this, when there's a ton of naysayers that say the 5.4 can't/won't make good power. :nice: I personally think you should've kept the bay white though, but that's just me.

I have all of the EGR hooked up. It has a modified bassani X pipe. It looks to me from the pics that the upr shorties would fit.
 
You need to do something with that alternator it throws off the whole engine. Should be fun.

I said the same thing..I tried to take the one in the pic apart to paint or powdercoat the housing, it broke. So I got aggravated and put a new one on it. I will prob go in for the kill it a brush or paint pen. It bugs me.

I went back and forth with the engine bay.. But it looked like hell.. and paint was chipping on the fenders and it was mostly yellow (i live on a dirt road) I cleaned it up and that didnt help..so I went black...looks great in person.
