the pistons are probe 10cc dished forged .020"

 

when they ported your heads did they cut out the emissions mask (swirl dam), and are your valves flat faced or stock type with a big dish?

 

no, they really only worked the intake to match up to the adpaters and intake. the valves are flat.

 

EDIT: With that...you should end up with a 41-42 CC chamber so your CR should land between 9.62 and 9.75:1 which should land you pretty close to 300rwhp out of the box on stock cams and intake. If we recall, Saleen S300 made 289/366 with a 9.4:1 CR and stock everything. A local made 340/340 with almost the exact same setup I have and a 278 grade cam but a cobbled together intake that messed up the flow according to someone who was there (he says theres another 100hp being lost to the intake issue... and taht person I trust).

In any case... I don't see a problem getting within spitting distance of 350. You've got a 15hp gain on your side from the pullies and water pump which will help a lot toward those final few ponies in your goal number and the cam you've got has shown easy 30hp gains on 5.4's. You've got the hardware to get there but I think you'll need a better intake. Once I've done my dyno run with my HPS intake against the stocker you'll know what kinds of gains to expect from that.

I'll have between a 10.25:1 and 10.65:1 CR with my -4.5CC dish, emissions mask present and flat faced valves. Hopefully that'll get me to a new high for streetable NA 5.4 2v

 

now i have comp cams stage 3 i thought they were 278's, but they might be 270's

 

i should have it done by this weekend.

 

Hi, I just joined the forum mainly due to this thread!
I am in the middle of building a new motor for my Cobra'd 20001 GT.
We are using an '04 Lightning block as a basis.
As the late Lightnings have forged pistons already we are using Manley forged rods as well to make it all stronger.
My original Cobra heads are being reused and we are using a Sullivan intake for the top.
We had to get a Navigator front cover but apart from that most of the other bits fit from my old Cobra motor and the Lightning.
I used to use an aftercooled Vortech but as the Sullivan intake is front facing it would take some modifying to get it all back on so we are now going for a twin turbo set up which is a bit ambitious for this side of the Atlantic!!
It's all going very slowly but I am sure it will all work out....

 

u have any pics of your build?

 

Sorry, a bit slow uploading them!
It's early days and we just dummied up the heads and intake to see the fit and size of it all.

 

you're giving me a raging clue. Beautiful setup.

What are you going to do about hood clearance? 2000' Cobra R hood would probably fit pretty well and clear the intake. You've got enough motor there for darned near unlimited power. Have you given any thoughts to what your target power level is?

 

here is my project. all i need now is a clutch and some odd nuts and bolts...

 

you gotta buy one of my sets of adaptor plates. I have a shiny set of Reichard's. You may need to resource some attachment hardware but those are easy. It'll give you back like a 1/2" of hood clearance

 

Would you guys consider this a pretty good deal on all the forged bottom end parts?

http://cgi.ebay.com/ebaymotors/4-6-F...spagenameZWDVW

It's all name brand parts and the companies may not be the high end but they are respectable names. I don't expect the parts to last to what he says they will 1000+ rwhp, but I would expect at least 650...700 tops.

 

that's totally the wrong kit for a 5.4L combo... gimme a sec and check back

Call up The Mustang Depot, ask for John. Tell John the guys doing all the 5.4L swaps sent you. He'll probably remember... we did a GP with them.

You can get probe or Mahle pistons for about 520 with rings. They're top shelf stuff. Let me know if you'll be using boost and how much and I can help you with the dish size. They sent me perfect circle file fit rings with my probe slugs.

They also sell a 4340 forged H-beam 6.658" rod that you'll want. Those are 320 (and a screaming deal at that... they come with ARP 2000 bolts)

http://www.ddperformance.com/images/ford_flywheels.htm for a flywheel.

TMD should also be able to source you a good 5.4L crankshaft. Make sure you get a forged one if you're going to go nuts.

 

if i could afford them i would
these are ported to match the intake andd heads

 

those are from the original run the magizine had made for the buildup article they did.

 

I'm not going to give you the ream job... lemme know what you can afford and I'll see if I'm feeling benevolent. Never know

I do have 2 sets of plates... and only 1 motor that needs them

 

how much better are they then mine? if all the diff is 1/2" then i'll keep mine, i'm sure the engine loves more air...
but seriously right now i'm trying to get her running, i have all old cars at home and i ned to replace all of them so i am broke as hell right now. any powdercoating i do goes to this project to finish her.

 

Sorry I was tired this morning and didn't post the right link and now I cant find it here is the rotating assembly kit I was going to get.

//
Full rotating assembly kit for 5.4 engines including Manley forged pistons and H-beam rods, forged steel crankshaft, SHM moly piston rings, Clevite rod bearings, and Federal Mogul main bearings. The quality doesn’t get better than this for aggressive street or moderate race applications up to 700 hp, 7000 rpm.

Pistons available in standard size or oversize 0.020” or 0.030”, and flat top or dished 17cc or 23cc.
Please indicate desired piston size and cc, etc.
//

Is this a good deal for $2000 shipped to my door? Brand new parts, I'd like to stick with brand new parts considering everything else is brand new so far. I would be going with the oversize 0.030". I want to go with a single turbo so what would be the best dish size for a boosted application.

The turbo is a T04E V1 more details if anyone is interested.

 

I already have the full 2000 Cobra R body kit fitted.
I read that you have to mod the K-member to reduce the height by 12mm as per the Cobra R. Any lower and it hits the steering column.
I have a UPR tubular K-member so it should be straight forward to do.
As for power, the set up should be good for well over 1100hp but I want it reliable as I have to travel long distances so we think around 850bhp should do the job.

 

everybody says you have to modify this and that. take it from me, i have had mine in for over 2 years and i didn't mod anything. i spread the exhaust apart with brute force to get an extra inch to bolt it up. i used the stock mustang engine mounts and it fit perfect. the only thing you need is the adapter plates and thats it. check my link in my sig, there are a couple pics of the old 5.4 in there.

 

They're about an inch tall maybe a hair less. They're definitely shorter and you can hog them out for a gasket match pretty easily. Your option... I'll still have them down the road a bit so if you find you can afford a couple hundred then you can still pick them up.

Moose: K-member does NOT have to be modded at all.

Blitz: That setup is mostly fine but Clevite 77's don't do it for me. Use hardened bearings without a tin overplate or you'll shred them at the power levels you're looking for. 2000 is a bit tall. Call up the people I linked and talk to them. I'll bet you can get all that stuff shipped for just over a grand. Leaving you money for ARP head and main studs and a windage tray.

I don't know if the T04 is really big enough to feed the 5.4. They come in a lot of sizes most of which are not that big. Make sure you consult someone familiar with sizing turbos for mid-size v8's before you buy the compressor.

 

myillwillinc, Just checked your car out, very nice.
So I don't have to modify the K-member then? I am just wondering that as I have the 32v heads if that is still the case.
What are those adaptor plates you mention?
I have heard of plates to enable you to fit the 4.6 intake but I am using one of the just released 5.4 32v intakes from Sullivan. I think mine is one of the very first produced as it was collected from Sema this year and my friend is still waiting for his!

 

951-369-0200 that's the number for TMD... they have the best prices I've found on forged goodies.

Ford dropped the engine on custom mounts to clear the intake. The 00' R intake is very tall and they had issues with clearance. Headers may be an issue... You'll probably have to have some custom made or at least custom modded. Check out Bassani Mid-Length headers. They're a weld together setup so you should be able to make them work with a little tinkering.

Adapter plates are available for 4.6 - 5.4L in 2 and 4 valve types from Reichard Racing. You don't need them with your current intake but I'm still a little tiny bit concerned about your hood clearance wtih the Sullivan. The Sullivan is a very nice intake and shows wicked powerband shifts. You should be happy with that. Check out http://reichardracing.com/46to54adapter.php for more adapter plate info.

 

I wondered about custom engine mounts but all I could find was that Ford modded the K-member.
I have seen photos of a similar Sullivan intake on a 4.6 Cobra and it seemed to clear ok so that's inspired me! They have only just started to make the 5.4 so I will have to report back to them on how I get on.
As I am using twin turbos the headers will probably be shorties but turned around.
It will be snug whichever way it goes....

 

since myillwillinc has such a nice page for his car, I redid my index page for www.squarerootofone.com and put mine together. I'll update it as I get more pics. I have quite a few that I need to take for historical purposes anyway.

Have fun bending that exhaust piping. You'll be able to see 1000hp with two of those hair dryers pumping the air in. If you have a project page link it up here so we can take a peek.

 

The only project page I have at the moment is on a European Mustang website I belong to; http://forums.mightymustangs.net/ind...dpost&p=178771

 

look what came for me today...( really i went over there since they are 15 min away from my house...)

 

got the underside done, now to find a couple bolts to get it ready to drop in this week.
