The typhoon on adapters lost Saleen S330 (testing my typhoon intake) 10hp and 26lbs of tq off the peak and never showed any promise to my eyes even on 4.6's... I don't know where they got their numbers from but they didn't show up in the dyno results. Kinda a shame. It was a pretty looking intake.
Guessing on peak returns isn't going to be a good idea because it's just a guess. Given that the flow path is much straighter than with plates I'm betting on a solid 10-20hp gain and nice area under the curve gains especially on cars with longtubes. Cars with stock exhaust manifolds or shorties... they may not gain much on the peak but the powerband will almost certainly be better positioned for a sports car application. The trucks peak tq below 2900rpm which is useless for us. We want the peak tq up closer to 4000 or so rpm.

no 5.4, not for me. i sold all my 5.4 stuff to a friend of mine. now he is unable to finish the project so it is all up for sale.

I'll take one,
and I guess I should give alittle background. I've got a 97 GT and I've been keeping an eye on the thread. The swap only makes sense for me since a PI swap would be about the same price. I've got a complete '03 5.4 and I'm left needing an intake, cash in hand, so to speak. I'd also be interested in a set of longtubes later on.

That would make sense.

For anyone looking for an engine, there's a crashed Expedition on eBay selling for $700 for the entire vehicle that isn't too badly dinged up. Plus, you can always part it out to make up for the cost of your build.

Too bad they don't offer cheaper Iron versions or 5.4 versions. In fact, too bad they don't offer any serious parts for the Mod engine. All that FRPP offers is a 4V cam kit, 4V head, 2V head (which uses the old NPI style ports), ported 3V heads (why can't they offer the same for PI), valve covers, and 4V intake. It's time they expand their offerings to the level they offer the W/C SBF guys and 385 BBF huys.

To the guys running the 5.4 h beam rods off ebay, do they weight the same as a stock rod or are you all having the rotating assy rebalanced with the new rods? I have been told that on a lower revving engine you might get away without a rebalance but Ive allways had them rebalanced but have allways put together high revving engines so perhaps there is some truth to it?
Also, are the lightning shortblocks the same as a standard 5.4 shortblock(same rods, etc...) as found in say an expodition?

you'll want to have it balanced. There's enough part changing going on. No reason to cheap out on the cheap part.
SC Lightning motors came with forged pistons and stock 5.4 PM rods. All the rest of the bits are the same. NA 5.4's came with HE cast pistons and PM rods. IIRC only the 2000 Cobra R came with H-beams in a factory 5.4 modular.
FWIW... I had mine balanced and blueprinted. It's a quick revving sumbitch! 12lb flywheel or no it'll ramp some RPM fast.
I fired the beast again last night so a friend could hear it. Damn thing is LOUD and nasty sounding. I'll see if I can get a good sound and video clip this weekend.

I'm talking January-ish was the time Bob was looking for. I'd figure shipping to purchasers by at worst feb.
Let me be frank for a moment... we know for a fact that at least 50% of those that say they'll buy a first run will not. That's life. So if you really really want a first run, you'll find a way to finance it by then... hell put 50 bones a week aside and you're half way there in the WORST of cases. We're going to basically take the number of peeps that say they'll take one and cut that number in half then add a couple units for slop. I'm betting they FLY off the shelves since it's the absolute first intake made for the application.
There is no real deadline for pre-order. I need to try and have a good solid estimate by end of week since the order has to be placed at the foundry. I've got 4 100% solid takers not including me at this point. I'd like to be able to tell Bob to produce at least 15 or 20 as that makes it more worth it but I don't want to inflate the numbers either. In 24 hours we've got 5 units basically sold so I have high hopes.
If you think you might be able to pick up a first run and you're intent on one day owning one... put your name down and I'll take care of the rest. Each yes answer is only going to be 50% of a yes anyway so you'll not be held accountable to your intention. There's no way to lose out. Also... this is something you can buy and sell on ebay if you want.

couple more questions.
Front timing cover-is this the same reguardless of head chosen? if its diff how(besides making a custom cover or modifying a stock 5.4 cover?) to make it fit?
b heads- anyone ever ran a set of b heads on a 5.4? Any 5.4's ever came with b heads?
b heads- do the mk8's and cobras use the same cams stock?

02 Mustang 5.4 swap :)
Ok guys my eyes are now bleeding from reading all of these posts >< lol...
Thanks for all the great info i've read already. I have a 02 mustang Gt 5spd car (tr3650). I am now working on gathering all the parts for my engine build, and I have a list of my plans. I'd like any suggestions from you guys on my swap.
1. I got a 98 5.4 complete longblock for free includes timing cover and everything but accesorys from which i read all my 4.6 parts will fit for that. I believe I will need to buy a 5.4 tensioner though.
2. 98 will be a steel crank from what I read yeah?
3. I plan on using my PI heads from my current 4.6 in my car with some porting.
4. I am gonna go with comp cam 270 camshafts and comp valve springs.
5. I will need a cobra flywheel (8bolt) and a cobra clutch for use with my tr3650? I am planning on getting a Centerforce DF clutch.
6. I will be using adapter plates or Hardballer intake if its ready to go bye the time I am. /hopes...
7. I am gonna rebuild the lower end using Hbeam rods and forged pistons, what is the best Compression to run for this? I dont plan on supercharging or turboing it. Maybe I will nitrous it a small amount some day. I drive this car alot on street.
8. I have a Upr hpipe so from what I read I'll have to have that modified to fit which if I cant do it I can easily find a exhaust shop to do this.
9. Atm my 4.6 has the K&N Fipk kit and Bbk upper plenum and 75 mm tbody, and flowmasters, and a Diablo computer. Which all should work with a 5.4 yeah? I have a great local shop to do the Dyno tuning once I get it together.
10. I have 3.73's now so from what I read ill probaly have to switch them out.
11. Will this fit under my hood on my 02 gt? I have the factory hood scooped hood? Will just some cutting be enough?
12. Any of you South Carolina ppls know of any good modular machine shops in the area?
Im very excited to get this goin so any hints or constructive criticism would be aprecciated.
Thx again Bryan

Yep... should be a nice strong crank. It'll take whatever you can throw at it.

if you want you can try my theoretical-best-grind-ever cam spec: 226/244 @ .050, .535/.550 111.5LSA. That should be wonderful on tq all the way across the band with a nice smooth hp delivery out to around 6K where it'll start to lean over. That's perfect for a street stroker. LMK if your grinder wants more details on the cam. Install straight up for smokin power.

Stopped by machine shop and snapped a few pics of new motor. Also found out that the factory deck hieghts where about almost .010" different front to back on each bank. Had to resurface block they are now withen .002 and pistons are exactly .100" in the hole to give me a final compression ratio of 8.5 to 1.

w00t. almost done. Looking good.
I did my first break-in oil change this morning. Cut open the filter and checked out all the nastiness in it. Looks like the rings and bearings are seating just fine with no major flaking. All signs are still looking good.
I'm working on getting my tune refined and stable. I've got it streetable for break-in but I'm not taking it to WOT till it's got a couple more oil filter changes on it.

when i was in auto mech school i had one teacher that said 500 miles to break it in and another that said if you built it right you can flog it the first day. so i'm still out on which is better. i've used both methods with sucess and still haven't picked the better one. this motor i haven't taken it over 2500rpms but that is cus of the fuel issues i was having. plus i have a brand new clutch to break in also...
