16pounds in a 5.4 is FAR from mundane... think life changing. With a proper tune and 8.5-9:1 you're going to be looking at 550-600+hp and similar tq. Get a Hans device.

Your engine build approaches wild other than lacking ported heads. It's definitely Ford tough and the cams and bigger valves will help. Your old motor seemed to be a lot more sedate but I don't know if you were using the comp cams on it before it blew so that's an assumption.

Here's my take on that... take it away bassman: The cold tranny blues gets us all. Once mine warms up it's silky. I call that broke in.

My motor would be what... probably a little on the wild side what with all the intake and multiple nitrous systems and such.

BTW... I had a wreck last night. It wasn't super bad but it fugged up my front end body work and impact bar pretty well. Airbags didn't go off. If they total it out (I doubt they will) then I'm going to have to buy a Kia to settle a deal with my wife, which would mean I'll buy the damned car back if I can or sell you guys my ****.

 

Crazy, i almost wrecked mine before i blew my clutch. Seems in the air around where i live. Glad to see your ok.

I CALL DIBS ON EVERYTHING lol

 

Hey everyone.

Figuired I'd check in to the thread here. I have read some of the threads on ModDepot and have been a searching fool on SVTP and NLOC/NHTOC looking up 5.4 info but I found this one on google - best 5.4 swap thread so far.

I have a 01 GT that I will be starting this swap on here in the next month.

I am buying all the goods for a fully forged shortblock right now (Manley pistons, modmax rods, etc etc), and will be sending them to MMR to be balanced, then doing the assembly work myself with the help of my fiance'.

My plan is to put the motor together with stage II heads and blower cams and hope thats enough flow for the 5.4. It will be n/a for about 6 months while i upgrde the trans/fuel system/rear end, then will get a vortech. I'd like to use the edelbrock intake if its released by then, but will probably end up using the RR intake and widening it.

I saw the post on the 5.4 roush about 10 pages ago, that had the L lower intake and cobra upper intake and dynoed 340/340. I'm assuming thats because of the lack of runners in the intake ? With an intake like the RR or Bullitt with some plates shouldnt a similar car be in the area of 320/380 ?

Thanks all, look foward to the next 100 pages of this thread.

 

good to hear it man, good luck on the swap. I also am wanting to go the vortec root. let me know what you do about a cooler. cheers

O and i would seriously look into that trickflow intake comeing out. i've heard that its bad ***.

 

Well man , i'm sorry to hear about your car. On a different note, i'm not sure about any of that 5 speed stuff since i'm completely retarted when it comes to that. i know autos but i'm trying to learn. i just posted what i heard with a side note that i wasn't sure. Redneck, i was talking about the starting 5.4 i'm going to put in is going to be mild, then i'm going to vortec later. Hans device lol thats classic. Anyway, i'm going to pass on that 5.4 right now since i ran across some windsor heads for a steal. so i'm going to take them.

 

I've seen the TF prototypes, but I'm not a fan honestly.

I want to widen an intake instead of using adapter plates, I'm going for the whole sleeper thing, and the adapter plates are a dead giveaway. The TF and Bullitt both look to be a PITA to widen.

The edelbrock or RR could both be widened fairly simply which would also increase the plenum volume, someone posted that on one of these pages of this thread, I forget which one though. Then I'll just use the Sullivan upper and tell everyone its a custom sullivan 2v intake

On the cooler, I'll go Air to Air most def - the largest one I can find. I may also get an aftermarket air/water and try to hide it in the fender somewhere - but that could be my overkill drive talking. I'll need massive air cooling though, because it gets hot as hell here in the summer, and I plan on boost stepping and running 25ish PSI into this bucket.

My concern is the Vortech bracket / timing covers. I want the accessories to be in a stock location, and the Vortech in the stock 4.6 location. If I could run the L lower pullies and dual belt - one for the accessories and one for the blower that would be even better. However I believe the inside belt is the accessories on those, and I'd want the inside belt to be the blower - which means shiming ALL the accessories. Probably not a good idea.

FWIW, If you cant guess. My imagination and overkill tend to get the best of me ALOT

 

Damn that sucks r3d. I'm glad your ok, and I hope I don't have to see you driving around in a Kia. It would be very tempting to scoop up that 5.4l stuff from you, but I'm sure everything will work out and you will be driving a 5.4l beast soon enough.

 

I hear ya on that one man. i want the vortec to be in the same location, but i want mine to look just like the 4.6 too , so i'm getting the plates and painting them to match the intake. around where i live no one has heard of the 5.4 swap

 

I'm not totally sure that the 4.6 vortech bracket won't work on the 5.4 front cover. the only spare 4.6 front cover I have is melted so I can't even run down and grab a bracket to check fitment for you guys. My intuition tells me that it would probably work pretty easily.

As for intakes... the intake that my local guy used had a couple imperfections. 1 was a huge lack of runner length. I think the hp would have stayed at or very near 340 but his tq would have gone up if there'd been longer than 2" runners and 2, something more than a giant box as the plenum. The upper intake hat he used was probably the best thing he did.

The Hardball'r I've been working on demonstrated to me that a flat bottomed big box plenum like the lightning lower has some definite turbulence problems. All the air comes in, hits the floor and jets to the corners. If you round the bottom just right though it seems to help the balance. Granted my tests weren't conducted under perfect conditions but I tested enough with plexiglas bottom covers in flat and curved shapes to get the idea of a trend.

With the prototype plates I'm using and the general external appearance of my intake I'm betting I fool everyone but the hardest core enthusiasts. they'll look and think they see a 4.6 with giggle juice and a black intake and then they'll race a 5.4 with giggle juice. i'm going the matte black paint route and just hope the smog tech is distracted by the fuel rails and nitrous kit and doesn't notice the bulk of the bigger block.

 

Yea r3d,
really sorry to read that... ..but i know you'll be back in it...check this out i got this today from MMR "well if you are running a T-trim i would run are stroker motor it will pass smog and i had a customer make 726RWHP with a T-trim." i sent a response today asking if they meant a 4.6 stroker or a 5.4..i'm thinking 4.6 so I will post what ever response i get...i'm sure if i run those types of numbers i can get the chevelle...and a few vettes...maybe vipers...it's all in the driver not the car...LOL..thanks for taking the time to read this...

 

Hmm, that brings up a change in plans.

What do you think of the widened Bullitt intake, posted on page 2 or 3 of this thread, as compared to the other options out there? I saw that guy also increased the plenum volume, but hes in the low 200ish RWHP range, im not sure why.

I was thinking of doing that, or widening an RR intake but I've read the RR looses torque down low, and I'm building the 5.4 to get the torque.

Any details on those proto plates ?

Do you think the Stage II ported heads are enough flow for a 5.4 n/a as well as boosted?

 

stage 2 heads are fine. stage 3 isn't enough gain to pay for.

intake options are all over the place. I have a design for the lightning lower I'd like to tinker with but I have no time or resources. If you're up for a little experimentation and want a serious purpose built intake, PM me and I'll fill you in on the design I'm thinkin' of. it'll require significant TIG welding to be done inside the plenum but it'll be worth it if I'm right like usual. I'm confident in my HPS intake with all the porting I've done. I think it'll turn in good power and tq.

 

To widen the Bullitt intake is more trouble than what it's worth. Too much welding and cutting is required.

 

why not just put the addapters on it?

 

I'm trying to hide the fact that its a 5.4, and the intake adapters give it away.

 

I'd love to hear what you have in mind, I'm always about ideas and new stuff.

Whats the latest from HPS with the 5.4 2v version ?

 

ok, finally getting somewhere with this car. got my k-member in today around 3pm. been working ever since. got the k-member in and the steering and a-arms. went ahead and dropped the motor in. this weekend i'll get most of the rest done.

 

willinc,
Looking good....can't wait to hear it...i hope when you get it done you can grab a sound file for me so i can get an idea of how bad these "beast" can sound..LOL...especially since i'll be over seas and looking at this forum is what will keep me the most sane....i tell people all the time as long as i can check this forum..and get my mag through the mail..i'll be a-ok..LOL..so from the time i leave to when i get back i will be counting on all of you guys and your post to keep me alive...LOL.. ...thanks for taking the time to read this...

 

well you will get tired of seeing my post lol if your not already anyway, myillwillinc that is looking so good man. The black does look good with the gold. A+ man

 

I figure if you take a plate of aluminum and bend it so it has a distinct curve at the bottom (kind of like what would happen if you placed the plate on top of the lower and then leaned on it to shove it into the plenum... hope that's clear), then weld it up inside the lower. this should help the air move evenly up the sides after it comes in from the top. then weld up some thin wall aluminum 1 5/8" tubes that follow the newly revised walls from the existing runner opening to the bottom of the common plenum (this will probably require a drawing) where they merge into what I think of as a bath tub. In general the design is kinda like long tube headers inside your intake but the tubes should only be maybe 6" long each in total, not counting the existing runners.

That'll create a mid-length runner and a badass nitrous intake. The top I would probably make from a 96-98 cobra upper so there's more volume and a consistent curve to the roof and floor.

The HPS 5.4L version is in their hands. I'd bet it's a year or so out.

 

I have some video files of Saleen S330 getting a dyno run and tinkering with the Typhoon intake on his car. I'll post em as soon as I get a chance.

 

nice, i would love to see that. Sadly i passed up that 5.4 on ebay, but i got a set of pi windsor heads off a 5.4 with the v/covers for 195 shipped

 

I'm not exactly sure I follow you on the intake idea you mentioned... Drawings would definatly help.

I'd love to see those vids as well.

I'm still waiting on my comission check so I can get this project rolling. The wait is killing me, I have a whole list of everything to buy ready and waiting. Money's spent before I even get ahold of it, haha.

 

i wont get tried of it trust me...this is my 4th mustang...i love checking these out...this is what i got from MMR today "i am talking about the 4.6 stroker. it would be more cost effective for what you are trying to do and make great power." so i think i just might go for the stroker even though i know more tq is from the 5.4..i'm really stuck in between on what to do.....i just read an article talking about a 502 that made 502hp and 572lbs..so hopefully i can make that easy enough on pump gas and then later on jump up with a t-trim on it or i might even look into what r3d is doing with the nos...is there still a way to have the nos kick in once you hit a certain rpm...that way it's automatic instead of having to turn it on...thanks for taking the time to read this...

 

yea its called a window switch Stang671. turns it on and off at a certain rpm

 

does it cost a lot....is it worth it..dont kick me off this 5.4 forum is i go 4.6 stroker cause i really value all your opinions about this stuff...thanks for taking the time to read this...

 

i'm not really sure how much it cost but i know that most people get the msd one but i'm thinking about the dynotune nitros people. they have a really nice one on there. i can't remember how much for it though. It is worth it, since it won't activate unless its in a certain bracket. so its a messure of safty and reliablility. i think if it cost 1000 bucks it would still be worth it. Hope it helps. Just go check some out on different sites and stuff. that should answer your questions.

 

window switches are cheap... they're not even costly enough to wimper about.

4.6 stroker is nowhere near as potential laden and you have the disadvantage of a decreased rod:stroke ratio with the short deck. The 5.4 is and always will be more powerful than the 4.6. If you want to poke and stroke the little block... that's your bag. You're still welcome in here.

500hp/tq isn't really difficult with the modulars and particularly not with a 5.4 modular. It's still expensive but there's a hell of a lot more room left in a 5.4 at 500rwhp than there is in a 4.6.

 

ok..i'll send them an email and let them know that i really do want the 5.4 cause i really do cause it really seems like a great swap...so that's why i'm really counting on you guys to keep posting info so i can keep up with what to do...and at 500whp what does the usually = at flywheel...thanks for taking the time to read this...

 

I am currently thinking about doing a 5.4 swap. but i look at my engine bay and since its a convertible i have the strut tower brace? or can i keep it on?? then i was also told that 3.55 gears would be good, or should i do 3.73??

thanks
