JScott1176 -2V 5.4

[SONICBLUE4.6]

Sweet I have actually picked up my 5.4 2v from an 02... I am going to get the adapters and P.I. intake and do the swap......

[96blackgt54]

I'm excited to see results from the new Trick flow heads on the 5.4l.

I think the head is to much for a 281c.i. engine, but just right for a 330c.i.

Will be interesting to see how many die hard 4.6l guys go 5.4l

Here was ideally what i wanted to do. NPI bottom(forged crank), flat top pistons, better rods, my ported PI heads, Hardballr intake, XE278AH, stock manifolds. Id like to run a 125 wet shot but i know ill need a better pistons for that. Hopefully the intake and cam can move the power up further so i can still use my 3,500 converter. Id hate to take it out just to drop it down to a 2,800.

That all sounds like a decent enough plan of attack for this project. I would expect to see 280ish rwhp and 330 rwtq thru your automatic. You may be better off with a 2800 stall only because the engine is making max torque at 3500, and set it to shift at 6000-6200. The only other thing I would change out if I were you is the gears to 3.73:1

[Floordford]

yeah i actually have some 3.73s laying around that i want to get in there even with my current set up.

Was also wondering how the extra weight feels up front. Ive read that its an extra 60 lbs and that a tubular k-member can offset the weight difference. I didnt know if i might need to add thicker spring dampners up front.

[jscott1176]

It is roughly 50-60 extra lbs on the front end. The only place I really "feel" a diffeence is on the racetrack. The car has a bit more understeer now. As far as upgrades to the spings and dampers (there is no "n"), you should be fine with what you have. Even with the stock 450#/in springs, an additional 50# load on the two front springs will yield an additional 0.05" drop. I plan to eventually upgrade to the Maximum Motorsports K-member as well as move the battery to the trunk. That should more than offset the weight difference.

My bad on the "dampner". I think its just the lazy way every one talks. That sneeky N found its way in there. Good info. I was worried because im already lowered. And i think the only aluminum block they made was for the GT and GT500, right? A guy wanted $3,000 for a bare block on ebay.

I'm an engineer and it's just a pet-peeve of mine. To dampen is to get something wet.
The only aluminum 5.4 block is the FordGT and it's only setup for a dry sump. The Shelby uses the same iron 5.4 as the rest of the world.

[Floordford]

Ahhh, ok.
I was tossing this idea around too. Sticking with my SCT Xcal2 hand held or swapping over to Mega Squirt. I havent done my homework yet on all the details of Mega but it looks like you can get into some nitty gritty tuning with it.

For people just freshing up thier stock bottom end 5.4

How much did you all end up paying for rod bolts, main bolts and gaskets?

Also what machine work do you recomend on preping a 5.4 I know mines need a hone
