i use 225's with 90/10's and no swaybar. just fine on the street as long as you dont run it hard on bumps or around corners above 120mph.

 

anyone know someone selling a forged 5.4 crank? mine has to be turned .030 and i'm having a hard time finding anything other than stock replacement bearings that are more than .020

 

KarKraft was selling them on ebay for like....$90.

I may have one laying around or in an engine. Let me go look and I'll pm ya.

 

The 5.4 I got Has a Steel Crank in it. I guess the F-250's came beef'd up. But someone told me the OEM cranks were junk. Does anyone know?

 

stock cranks from any year 5.4 are bodaciously strong out of the box for a stock piece. I would probably start looking at a higher end forged unit from Kellog/Manley/Eagle/Scat etc... after 600rwhp in a car or 525 in a truck.

There was one or 2 years that had a forged steel crank stock but most 5.4's come with a cast steel unit from my understanding (this is minutiae that isn't normally a concern). I don't know of any definitive tech matter that shows any cast iron or nodular iron units. Wikipedia's article on the Modular engine family specifies that all 5.4L 2v's came with forged steel cranks.

Fact is unless you're going nuts on power it's not an issue of concern.

 

not to counterpoint the 5.4 crank . 04+forged pieces are used by Al in nearly stock condition to 8200rpm 597rwhp.

Hey Bondfreak!
Glad to see you made it over here! You'll come to find out that a lot of "engine tech" from that Vic site has no foundation. The stupiditiy from that site racks my brain!

The engine tech you will receive here is second to none!
I can not see how somepeople can post 20,000+ post and can tell you what, how, and the problems from building "ANYTHING". You will find that their are alot of non-since post over there.

Assasinator....
Nice info! Thanks

 

Did a little Excel mashup of my before and after dyno numbers from just the swap from my 4.6 to my 5.5. The 4.6 was simple bolt-on equipped. The 5.5 graph is from the shakedown dyno of mine you've all seen.

 

What Kind of intake should go with for my 5.4? There are lots out there and I have read about them most of them, it's just hard to pick. I know about the hard baller intake but I already have the 4.6/5.4 adtapters. Should I wait anyway for the new hardballer? Or should Stick the PI, go the P51, BBK? Professional Products? There are alot out there. I have read the reveiws and the dyno graphs but I want to know the guys who ues them think.

96black54. The IQ in on this board out ranks the CV Board when it comes to the truth on these Mod motors. It's just dumb to the think that mods for the Mustang 4.6 will not work when it's the same damn motor as the Crown Vic 4.6

R3dn3k, your Pony has a 5.5 liter. How far if you bore your 5.4? .030 over? I was thinking of the same thing myself
also for your graph...which lines are what? I'm sure I can guess but I want to be sure.

 

yellow and light blue are the hp and tq from the 5.5, dark-blue/black and purple are the 4.6. Light blue and purple are tq.

The HPS intake solves problems and adds performance capacity. It's going to get optimal dyno results from a mild to moderately cammed motor with ported heads and longtubes (for NA cars) and any kind of forced induction will love the HPS intake. ProProd intake is t3h l0se, P51 is for blower cars. BBK may be a good unit. I helped spec the design of the%2

 

I was heavily looking into the HPS intake so thanks for the info.

 

Sheesh this intake is taking forever! Woulda been almost faster to mine the metals my self!

 

if this intake doesn't make an extra 100rwhp there is gonna be an angry mob......







lmao...

 

"Patience is a Virtue young grasshopper!"

 

oh i'm patient here since my motor is coming back out tomarrow.

 

1.5" for the ones I made, others may be a little shorter. You've mentioned Hitech a couple times, you in the Twin Cities area or have just seen them online? I've done some stuff with Hitech including all the testing/tuning on the original 5.4 swap I did.....

 

i need the intake soon


dropped off the rest of my stuff and the machine shop today and he said he would start on it after he comes back from vacation next week and it would be finished within a couple days of when he starts

 

Hello everyone,
As you can see I'm new here and after reading some of the posts I know I'm in the right place.

I have a 1993 Grand Marquis with the 4.6L SOHC and would like to swap in a 5.4L. As you might imagine I have tons of questions, but here are s few that I think may get me started in the right direction:

1- Which 5.4L would be the easiest to swap into my Merc?
2- What modifications should I be ready to make?
3- Is there a kit available to facilitate the swap?

Thank you in advance for your help and I look forward to all the knowledge I may gain from all of you out there.

Best regards,
Rivie

 

grivie -

1) a complete, low mileage one
2) adapters and exhaust tweak
3) this is a DIY deal still

but i have faith in you.......

 

Thx a million myillwillinc I'm working on possibly acquiring a 5.4L from a 00 F-150 (RWD). I’m trying to see if he will sell me the truck (it was in a wreck and the chassis is bent) but everything else is good: tranny, engine, ECC. So I may be on my way soon!



BTW, think we can come up with a kit for this deal? Bet we can make a pretty penny…lol…anyways, thx again and I’m sure I will be posting questions and progress reports once I start my project

 

Grivie, I'm working on this swap right now for my 2000 Crown Victoria. The 5.4 and 4.6 for the most part are the same engine. it will drop right in. you can even use the ECU from the Merc to run it. Now you do have a 93 but I doubt there is much of a differance in the engine bay. Remember the Panther platfrom(which is the frame these cars are built on) has been in use since '79 so any for motor from a 302-460 and any SOHC mod will fit. The frame was changed in 03 so the Marauder could fit a DOHC. If your part not part of the Crown Vic boards you might want to check them out. lots of info on the car itself. but they don't have much hot rod know how IMO.

also to save you some trouble If I remember the 5.4's got the PI upgrade in 01?(can someone check this?) so your better off getting an 01-03 5.4. any newer and you start running into the 3 valve stuff.

 

I dont think that is set in stone, I pulled apart a '99 5.4, which had PI heads on it and a forged crank (which was supposed to have stoped in '98) I think the build date on the valve cover was 11/98 and from what I read some '99s didnt come with PI heads, best thing to do is check the intake port if possible

There's one more thing to look for, the timing cover, the later (supposedly after '02) covers dont have the bolt holes for the power steering pump.

Heres a good link for that kind of thing,

5.4 Info

 

"NOTE" I'm stating info on NON-mustang cars.
Please do not assume this info is for Mustangs.
Glad to see you over here asking questions!
The 5.4l will fit in the '93 PANTHER, under the hood is a diffrent story. The wiper motor location would be an issue for the intake going to be used. The new HPS intake, I think would sovle that issue. Adapter plates and the 4.6l PI intake would just add to the already taller sitting engine. The FRPP shorty headers will work fine, but a good exhaust guy should be sorced first. And the wiring harness "section" under your incoming air intake will have to be cut & spliced for the newer style intakes. If you take off the air intake you will see what I mean. Not a difficult job, just a DIY kinda guy.

 

IIRC the 93 blocks used the windsor bellhousing bolt pattern. That could necessitate finding a tranny from a newer car or making a call to advanced adapters to see if they can/do make one. I don't play with much in the way of auto trans cars so I'm not certain.

 

Oh... BTW... I think I'm going to do a propane conversion.

http://www.mustang50magazine.com/fea...iel/index.html

Already working on the GP. LMK if you're interested.

 

what would the conversion cost?

 

probably about a grand plus a tune... waiting for a call back from the rep.

 

Where would you have to fill up at? I'd assume pretty much anywhere that would fill up tanks?
Theoretically, Could you use standard propane tanks in addition to their tank, since you get them basically everywhere and for added capacity *cough* rear seat delete

I was considering E85 but I cant find any thats close enough to justify it.

 

funny you mentioned propane i was just at exhaust shop the other day and guy drove up in an old school big block and i went wow what kinda gas mileage you get? He told me its running on propane... so i was thinking about that option or other fuel saving options.

Holy hell i just checked online fuel survey on prices accross canada....in edmonton where i live its 1.30 a litre (+0.1 for high test i have to run)for gasoline and propane is only 0.77 cents a litre. Thats a serious savings when a fill up costs 70 bucks;-)
