This is my first time messing with a cammer too. But the only thing I have done with these heads myself is pull them and take them to my builder who's doing the porting for me. He does a lot of Top Fuel stuff (he was Eddie Hill's head man among others, Eddie lives here in town BTW, I fly model planes with him from time to time, taught him to fly actually.... about 10 years ago). He said the last set he did flowed 330/275 @.550" and 28". That's just a tiny bit more than most of the other CNC'ers get (Fox, Patriot, etc), but he's slightly cheaper and no shipping! He's doing the assembly for free though, and that's usually around ~$200. It's a good deal. And he REALLY knows his stuff!

It just blows me away how much those 4v heads can flow! They are f^^king amazing!

For those of you who aren't "race engine savvy", you should be able to understand this way..........

A REALLY GOOD set of ported and polished, full-race, top-of-the-line, aftermarket heads for a small-block push-rod motor, and we're talking a motor making >600hp N/A, flows around 300/250 @.600 (300 cubic feet of air per minute intake, 250 CFM exhaust, .600 is the valve lift in inches..... or.... how far the valve is open for that flow rate)!. And those are ***** to the wall, forget driving it on the street, you're crazy and you're gonna die heads! And these ported stock 4v heads just eats their lunch without even trying!! I mean, they flow BETTER than A LOT of full-race big-block heads!!

God! This site is so slooooooooooooow sometimes!!!!!!!!!!!!!!!!!

 

nope!

i taped my eyes to.... nevermind, i didnt tape em they just glued themselves to something.

 

HEY .. you can tell me then! .. why did ford make a 3v 5.4 and 4.6??

I.D.K i can imagen the only reason being money and the fact that it could be cheaper to make a 3v setup with SOHC then a 4v setup with DOHC.

but if ford wanted to compete with the power of the HEMI and chevy vortex max and the new 5.7L Toyota engine and the Nissan 5.6 why doesnt ford simply 4v the 5.4? nissan 4v there 5.6 and look at how much more power they make ( while not to much more) is still more then a 3v triton 5.4 . sooo

what was Ford thinkin?

 

budget

 

thats what i cant figure out is what does this new 3v really have over the old 2v???

THE old 2v made only 10 less lbs/ft of torque and yet made it MUCH lower in the rpm range then the new 3v does.

old 2v 5.4 = 355 TRQ @ 2300 RPMS
new 3v 5.4 = 365 TRQ @ 3750 RPMS



WHY isnt this 5.4 pushing 400 TRQ ??

 

probably COULD if there was some porting n polishing done

 

Ford could make any of these engines into absolute power-houses. The foundation is there, the engineering is there. The simple fact of the matter is, they _choose_ not to.

Ford would rather have engines that are way over-built for the power that they make, and they would rather keep power down to keep miscellaneous drive-line failures down.

Increasing power isn't going to make Ford more sales. They know people don't buy Ford for their power. They buy Ford because of everything else. They are tough trucks. Lumping another 100hp in the feed bag isn't going to change that.

We all know the 70 tranny won't hold up to real power without blowing giblets, so they would have to ditch that right off the bat and go with the much more expensive 100. They would probably have more breakages, more abused warranty claims, etc. None of this is good for Ford. Since we, the customer, would be the only ones gaining anything from such a move, there isn't any motivation on their part to do it.

Ditching the 4v for the 3v.

The 3v in the Gator is only temporary. I have read in many different publications and on many sites that Ford intends to bring back the 4v at some point. But for now, going to the 3v over the 4, it gives the one engine for all the trucks, gators, expeditions, etc. So it makes smart businesses sense. The truck and stang buyers are happy for the little boost in power, and the gator crowed is content to gain and loose nothing (even though the 3v can't keep up with the 4v in the real world).

To get down to the root of it all........ Ford is filled with a bunch of cheap bastards who get to call the shots. Until the big 3 can dig themselves out of the big hole they're in, we will continue to see more and more of this.

 

There's not any way to take a 3v head and get the same valve area as the 4v. If you port the 3, you could possibly out flow the stock 4. But stock to stock, or putting the same amount of time and money to port both, the 4v will always whip the snot out of the 3v.

 

5.4 all the way
mine is reliable beyond all get out
i could pull down a house
and i can out run almost any mustang in town.
i would love to figure out how to get rid of that tick if anyone might know?

 

That's up to us I mean , what would we have to talk about then

Girls:

Motocross

x-WIVES !!LOL
I loved my last house , but so did she , that's why I don't have it lol...

 

well ford must be feeling the pressure from the consumer for a bigger engine because Ford is coming out with a new BOSS 6.2 - 7L gas V8 sometime in late 2008 early 2009. early guesses at power are 425hp and 425 TRQ.

and word around the camp fire is Ford putting i a 4.4L diesel for the expy and 150 around 2008.

i.d.k i like my current 5.4 3v ( i've never had a 2v) sure i wish it had more power to push this ungodly heavy *** truck, but it does a pretty good job for what it is..

 

[QUOTE=jbrew]you loser!

lol

 

whats really sad is whenever i come to this forum and come to this thread i feel like im home.

howdy neighbors.

 

o well, im gonna take the 150 out for a joy ride.

she may not be fast, but the exhuast i have on 'er makes me

cheers!

 

What's up dude!?
