After seeing many 05 stangs make near 500whp on 10-12#'s of boost and reading what Fox Lake can do with a set of 3V's, I started wondering how hard it would be to use a set on our trucks with our style blowers. I know Whipple makes a kit that includes an intake for the 3V f150's, so that wouldn't be a problem. The only thing I can think of is the variable valve timing. I'm sure there is a way around it. Anyone have any insight? There's only so much a 2V head will do and it seems like there is plenty of power hiding in the 3V's, with maybe not that much of a hassle.

 

Isn't Mike at MADD Enterprises using the 3V heads on his HD?

 

the variable cam timing is controlled by oil pressure, so that shouldn't be much of a problem. the intake is the biggie, but if you found one that will work, then it may not be too hard. nobody has done it, so somebody would have to pioneer it and see what else is needed. i am sure new headers would be needed.

and MAD is running a 4v setup

 

I wasn't sure what controlled the cam timing, but if it's oil psi, then ya, it should be pretty easy. Here is the link to the Whipple kit for the new f150's with the 3V heads. The intake and intercooler set-up looks awfully familiar.

As for Headers I don't think that would be much of a problem to tweak an existing set.
Here's a quote from Ron Robart owner of Fox lake talking about the 3V heads in a MM+FF article:

Fox Lake Power Products handled the porting and polishing of the Three-Valve heads. Ron Robart and his crew already have a CNC program specifically designed for the Three-Valve heads. "I think there is more potential in these heads than the Four-Valve heads. The port shape is nice and it's raised up," Robart says. He also mentioned the angle of the ports make it more like a motorcycle head, and the exhaust ports are efficient as well.

Sounds like I may have a new Project next year!

 

The Roush 5.4 3v kit for 04-06 f150 should work the kit uses a lightning
intercooler and other misc. lightning parts so one would assume a lightning
blower would bolt up?

 

I think you would need a computer from a 3V to control the cam timing, too??? I think???

 

Who says we have to use variable cam timing comp cams sells cams
now just degree cams and eliminate cam phasers all together.

 

Better yet what if there was a 4 valve lower intake that excepts
lightning intercooler and blower. 4 valve heads out flow cnc 2 valve heads
out of the box you could use stock 4 v cams and make 100 more HP
and truck would run just like stock no rough aftermarket big cam idle i know it sounds cool
but how about clean emissions and still get some fuel mileage cannot believe
ford racing hasnot added intake to catalog.

 

There is none yet.

 

If the variable timing is controlled by oil psi, I think as long as you run your own cams and defeat the oil psi to the cams, it should act just like our heads. I will have to talk to my tuner about it.

 

why do you guys want to eliminate the variable cam timing?

 

Mainly so I can use my computer to run it. Also because I would be using custom cams.

 

The varable valve timing is BOTH oil and computer controlled. The computer sends signal to solenoids that control oil flow to the hydraulic cam timing drive. This would be more work to control than its worth but like all things is do-able. I know Al P. (and others I'm sure by now) was just "locking" the cams in and eliminating the VVT drive on some high horse motors. There are also "Charge motion" flap deals in the intake ports........just as VVT to make work well enough to keep in a L just wouldn't be worth it. When they were on the 99-01? Cobra's everyone pretty much ditched them that made big power. I think Steeda makes the charge motion dele's with nitrous ports in them.

I do think the Whipple 3-valve kit and 3-v heads would be a fairly easy and worthwhile swap though.
