Anyone know of a performance intake manifold for a 2006 3v 5.4?

 

unless there's a supercharger bolted to it, I wouldn't waste your time.

 

YES do a ring and pinion swap

 

 

You need to do a top end kit to increase HP. That includes heads and cam swap along with the manifold.

 

Quality custom tunes and gears will make a huge difference. A tuner will be the best bang for the buck on your 3v

 

I plan on cams, a tune, 4.10s and short tube headers next (because I cant find long tubes) but as I see here the Intake manifold isnt worth it so that'll help put the funds elsewhere

 

What size tires? 4:10s aren 't much if you are changing r&ps. I went with 4:88s running 35s.

 

I heartily echo what Blamma and SDS said! Definitely regear but since you're going to spend the cash to regear you'll for sure want to go with a deeper ratio than a 4.10. With 31.5" dia. tires go with 4.30's if you don't tow heavy all that much. If you tow heavy go with 4.56's. Taller tires go with 4.88's whether you tow heavy or not. If you don't you'll be sorry. I have virtually no experience with tuners. I've seen pro's and con's both for and against but on thing is for sure, the gearing will bring the little 330 to life more than any other modification that can be done!!

Let us know what you decide.

 

Thank you, I'm currently on stock wheels/ tires. I wanna get 31 inch tires with truetrac lsd and I was thinking 4.10s. I do some towing but nothing serious I may be driving cross country to pick up a truck but that's the heaviest ill be doing. And by towing heavy how much would that be? Could I run 4.30s with the 31 inch tires and still pull 8k pounds on the highway without a problem?

 

Towing heavy in my vernacular means anything around 4 to 4.5 tons and heavier and don't forget wind resistance has a huge effect on towing capacity, as well. The definition of towing heavy will naturally vary from person to person.

Given your indications that you won't be towing much at all and intend to stay with the 31.5" diameter tires then the 4.30's and the truetrack LSD will probably be sufficient for your needs.

Personally, we tow between between 4.5 and 5.5 tons on a regular basis. Our truck is primarily a work vehicle that we also use to pull our 5'er and boat so we won't be opting for taller tires. However, even though I'm very much satisfied with the 4.30's I installed there are times and a few infrequent situations where I wish we'd gone with the 4.56 or even a 4.88. As I said, that is relatively infrequent. 90% of our annual mileage is towing, either the camper, boat or goose neck flat bed trailer so empty, not towing fuel mileage is not a concern for us. That is the perspective from which we're coming from. Your overall situation might be completely different thus making your requirements much different. All that being said, you will definitely want to go deeper than 4.10's and I honestly believe you will be far more satisfied with 4.30's. I replaced 3.73's in our unit and our empty-not towing fuel mileage may have dropped 1/2 MPG on average, for sure not more than that. But, we picked up about 1 to 1.5 MPG towing. Besides that your truck will be much more fun to drive with the 4.30's and I'll repeat, the 4.30's will certainly make the little 330 come to life.

 

thank you, thats the type of info I needed And you addressed the concerns I had. Right now I have the 3.73 rearend with factory lsd which I think is less than satisfactory. As for the 4.30 gearing do you have a company/brand and distributer where I could purchase the parts that you prefer?

 

Our truck was still under factory warranty at the time I installed the 4.30's and the Ford limited slip wasn't any better than an open rear end at the time of the regear so I took the differential to the dealer where I bought the truck and they put all new clutches, etc. in it while I had it apart. It wasn't long, even with the rebuilt Ford LS, before I was disappointed that I didn't go with a TruTrac. That's all water under the bridge but my experience suggests you're on the right track going with the aftermarket LSD unit.

I purchased my ring & pinion from Randy's Gear Supply. They deal with this stuff every day and the people whom I spoke with seemed to be sufficiently learned about what I was doing and what I would need to complete the regear job. I called them numerous times during the course of changing out the gears and they were always very helpful and understanding. I don't know if I could have saved some money by going with another supplier but given my experience the guys at Randy's and the assistance they provided was well worth however much I may have saved by purchasing the parts elsewhere, at least to me it was. The brand of gears they sold me are Yukon. I'm sure there are other manufacturers from which the gears would be available and you can probably get Ford OE gears but I'm sure they will be substantially more costly, and maybe they're worth it, but only time will tell. I've had virtually no problems thus far and I've put in the neighborhood of 30K miles on the truck since the regear. I'm not sure what the brands of the peripheral parts were since it's been a few years ago now. There is a break-in procedure that is required and that is clearly explained within the literature accompanying the parts. It's an essential aspect of the whole job and you'll need to concentrate on doing in correctly as per the instructions. Also, the new gears will be just a bit noisy within the first few couple thousand miles following installation. It will go away, or at least it did on our truck. You may have to do some reprogramming of the onboard computer but in our case the speedometer/odometer seemed to correct itself and adapted perfectly to the lower gear ratio all by itself. The speedometer is spot on and we never did anything in the way of reprogramming but your situation may be different.

Good luck and let us know how you like the new gearing.

 

I had 3.73 with stock tires (trucks a 04 so it's the 2valve 5.4 and 4speed 4r100) and I absolutely HATED the truck. It was completely gutless on the bottom end, I was always I to the throttle 70 to 80% for all situations. Went to a 285/76r16 and man did it get worse, ever 4wd situation needed 4low becase the truck just would not turn the tires unless I had my foot planted. I didn't think ahead at future plans so I had 4.30 gears Installed and man did the truck run then! Just tapping into the throttle you felt low end grunt and the truck just moved effortlessly. Since then I've hauled and towed numerous weights from 2k up to almost 9k and my little 5.4 does it no sweat. Now if I sat down and really thought it out I would have had 4.56 years with the 285 tires becase the highway rpm at 70mph is less than 200 higher and it would not effect my mpg plus that extra power down low would always benefit these big heavy trucks. Also if I would have thought Bout future plans (4inch lift and 35 inch tires) I would have done 4.88 gears....so now that I'm doing a four inch lift and 35inch tires this upcoming week I'm going to have to take it easy till I save up to do a 4.88 gear swap. Just trying to let you know my mistakes so it saves you some money.
also my 4.30 years are OEM Fords, they were the best price when I did my swap, also installed complete timken bearings install just front and rear
