Mike,

They said they tried just about everything, more duration, more lift, chang center line. When they finally got better heads then things changed but he could not tell me how was due to the heads and how much for the cam. Most of the notes are in R&D or sent back to Ford.
He seemed unsure of if increased lift only would help. I asked about the rocker and they tested using a measured 1.8 to 1. The stock ratio on the trucks is 1.75 to 1.
I am off to the parts bin to check this out.
On a positive note he said that as soon as he recieved my cam he would grind it to whatever spec I wanted.

Regards

Mike,

More info. I just got off the phone with Ford Motorsport's tech line. They say the same thing as Crane did about the cams. They have no specs on stock cams. So I can't even compare the 5.4 to the 4.6. They say that Sean Hyland is the only one they know that has done any work on the cams. The tech I talled to said he new of a person in Texas that bot a cam from Sean Hyland Motorsport and it did nothing for his vehicle. I contacted Sean Hyland and I will fax them a bunch of questions.

Regards

PS. What happened to the good 'ol days? Pull the rad, slap in a cam, rejet the carb and look out!

Mike T.,

After talking with you I contacted Crain Cams as you suggested. They have no offerings for the 4.6 engine. They performed extensive tests and discovered that changing the profile did nothing. They would get results like, worse low end and same high end or same low end and worse high end. Nothing seemed to produce results. So they contacted Ford and they concured with Crain. Unless you open up the intake nothing happens. They will however gring your cam for you, after all its your money. A camming we won't go.. A camming we wont go..
Hi ho the... ;(

Hi JMC,

As always, a pleasure to talk with you today. I would agree with Crane that changing the basic "profile" might not be worthwhile, obviously they're tried that, but increasing lift is almost always desireable, and adds power. The internal combusion engine is little more than a glorified air pump, and the more atmosphere you can get into the combustion chamber shy of detonation, the more power you make.

Did you ask them specifically about increasing lift only? And if so, is that what they said, that due to intake restrictions that this would not be effective? Did they have any specific suggestions on how to best alter the intake (different intake altogether, Extrude-Honing, etc.), or did you get the impression that this was something that they don't know the answer to?

And you thought you asked me questions....

It's a new day. Now it's put in a K & N Air Filter, a Cat Back Exhaust and call Mike for a Superchip.

HI JMC & T.,

They keep making it harder and harder to "cam" them, and then they wonder why we install superchargers.....

One way or another, we *will* have our power, said thr masses.

Mike,

Call me stubborn but I can not fathom why increasing the lift will not help. Needs more fuel maybe? Intake restriction caused by something? I will get to the bottom of this.

Regards

Jean Marc Chartier

 

Hi JMC,

My point *exactly*, more lift is always desirable as long as we don't run the valve into the top of the piston!

Perhaps there is some intake restriction that prevents additional lift from being efficient?

Let me know what you find on this, and what, if anything, they advise with regards to the intake so that more lift in the cam profile will do some good.

Aren't there some better breathing heads
out there? I thought I saw some in the Motorsport catalog. Or do they only work on mustangs? I'm at the point of improving the breathing on the sceamer
and thinking about some headers,and maybe losing my glasspacks for some Aerochamber mufflers. I just love the sound of them. What do you suggest,Mike?

Hi Screamer,

The Motorsports catalog is heavily slanted towards the Mustangs, that is true, as it's the Mustang that is Ford's main "muscle car".

As far as breathing mods, I don't know just how well your glass pack mufflers are working, but even if they were a bit restrictive, which glasspacks usually are not, it's not costing you much power, maybe a few ponies. If you want to change them, that's up to you of course, but don't look for big power gains from a muffler change.

Headers do work well, JMC has added them, Neal the HP Freak has added them, as have many others here on F-150 Online. The JBA's work well, and will add about 14 hp on the 4.6, and about 17 hp on the 5.4 motor.

So if you want to add headers, that's always worthwhile. Make sure to have them Jet-Hot coated, it's well worth the additional cost! And if you like the sound of your present mufflers, then I wouldn't change them.

Looking at your mods list in your signature, there is still plenty to do, if you want to go faster. (Watch out, this disease is progressive!) You can add headers, a nice 3-piece set of underdrive pulleys, and a conversion over to electric cooling fan(s) will all help to add more power get to the ground.

Good luck!

JMC

Over on the Corral there are guys with Mustangs prior to the 99' GT's putting on the 99' GT heads. The 99' GT heads have a more aggresive cam and better flow numbers. I believe these heads are actually the ones used on the 5.4L? Check it out it might work for you if the intakes match up. I guess Ford is raising the prices on these heads so you better hurry before they are 1k per head like the SVO's. The only other cams that are made are by SHM in Canada at $800 - $900 US per cam and I don't know the gains. Ford released the GT specs to SEMA, if we don't get some serious HP parts from that we might never get them. Sooner or latter these mod motors gotta take off with the aftermarket company's.

Good luck.

Headers it is,then. Can't wait. I heard somewhere that you have to jack the engine up,but a recently posted article in
another thread debunked that myth. I won't have 6 or so hours for the install until I get back to Houston in Jan. Just curious,does the comp.reset with the chip
installed? I love the glasspack sound,but still love the aerochambers(got
one on my 86 E-150) along with a 2 1/2 pipe. Single biggest gain I received on that van was the exhaust. I could hear the sigh of relief the first time I started it,lol.
So,is there a Superchip available for that vehicle? It is FI 302,1986 E-150,don't
know the comp. #yet. Thanks,,,,,,98

BigRed2,

Thanks for the info. I have already e-mailed SHM about their cams & heads but I don't expect a fast reply. It doesn't seem as if SHM has done much with the trucks, at least that was my impression when I phoned there. They wanted to sell me a super charger. I will check out the pn for the 99 GTs and see if they match the pns for the 5.4s.

Hi Screamer,

As long as that '86 E-150 van is computer-controlled and fuel injected, then we probably make a Superchip for it, we'll just have to see what the code turns out to be.

Those vans have more restrictive intake air tracts and exhaust systems due to less underhood room, so they tend to respond a bit better to the normal breathing mods.
