He told me that at the Ford dealership where he worked for umpteen years, the way they adjusted the 427 engine with the high overlap 324 degree solid lifter cam with the single four barrel carb (my setup exactly) was this: Turn the idle screws all the way in, back them out an equal amount for both, say one and a half turns, keep the rubber cap on the manifold vacuum port. Start the car and get it to running temp. Then adjust the carb screws equally so that when you pull the rubber cap off the manifold port the idle neither increases nor decreases. It sounds too simple to work but, I have to say, I am a convert.

Well, as what was said previously, whatever works. Sometimes we just have to think outside the box.

Yep, I don't even bother mentioning it to others.

It's always a plus to have a builder that's REALLY knowledgeable on FEs.
Right sized FE head oil restrictors is sort of "FE 101". O.125'" from jump street is waaay oversized, IMHO. Especially true if using a high volume/pressure oil pump.

Hi again Undy,

I'm hoping you're following this thread. I was wondering if you're also running push rod oiling or just through the head into the rocker shafts, etc.

And BTW, I am running a Melling high volume pump.

Thanks for your input Patrick. The more info one can gather the better we can over come our challenges.

Like Undy, I, too, am running Ersons with my Edelbrock heads and have limited the oil flow with .060 restrictors. Traditional, through the head, oiling. The Erson instruction sheet specifically called for .060, but that is generally right around what a lot of builders use with a solid lifter cam in an FE. Melling HV pump, Canton road race pan.

No, just through the heads.

Thanks Undy, was wondering if there is anyone out there running push rod oiling in an FE engine and if there have been any issues.
Everything seems good so far. The rockers sound good and I hear nothing out of the ordinary. My rockers actually quietened down to normal after installing the head feed plugs. The lifters are anti pump up rollers and therefore are slightly noisier than stock.
