After delving into the grey matter of what's left of my brain, I have come to the conclusion that it probably really does not matter what the size of the hole in the lifter disc might be unless it is smaller in diameter than the hole in the cupped ends of the push rod. The reason being is that the smallest hole or orifice in the lifter/pushrod/rocker arm is what is going to dictate the flow/pressure of this oiling circuit. If I remember correctly (big if) the smallest hole or orifice is the pee hole in the pushrod socket of the rocker arm that piddles oil on the rocker ball and indirectly down to the valve guide area. Please correct me if this isn not the smallest orifice. SOOOO, if all of the internal lifter pieces are similar in both of the lifters that the original OP compared, disc hole diameter size is probably a moot point.

Thanks, Royce for the good discussion and for FORCING me to think.

When I got the carb back from Drew, I adjusted it to the engine and set the timing using the max vacuum as target. It is pulling about 16.5 inches now from the PCV port at the back of the intake.

I will check the lines to the transmission next. Could the vacuum lines to the transmission and/or the modulator be leaking and still allow the 16.5" of vacuum at the PCV port?

Drew does excellent work, the carb performs exceptionally.

Thanks guys, Paul

Paul, you want the pcv active when you perform the manifold vacuum test. I would suggest installing a temporary tee in the connection where the transmission vacuum line connects to the intake manifold. The pcv is, by definition, is a vacuum leak. You want to determine if there are additional vacuum leaks.

Perform a manifold vacuum test on a warm engine, idling, and in park. I don't know the altitude of where you reside, but I would expect approximately 16 inches of manifold vacuum. If it is 14 inches or less, I would expect that you might have one or more vacuum leaks that you need to hunt down, like maybe the rubber hoses that connect the vacuum line from the manifold to the vacuum modulator. If it has never been changed, the modulator could be your source also. There could be other sources of leakage but try the easiest first. It is a simple diagnostic test to perform.

I hope this helps.

Making the hole smaller would increase the oil pressure.

My guess would be that it was done to decrease the oil flow to the rocker arms. I think that the smaller diameter in the discs would increase oil pressure to a very small degree.

Comp Cams sells a cam and lifter package for the HiPo as well.

You can question the numbers, but you CAN NOT dispute the original dirt. It would be a shame to loose that!

I personally think that the issue with the bolts loosening on the oil pan is caused by using a cork gasket?
Those things compress over time and that right there can cause loose bolts.

Doug is spot on! Cork compresses and rubber creeps causing the symptoms that the OP described. If one over tightens sheet metal engine oil or trans pan bolts, it distorts the pan sealing surface and causes increased oil leakage. There are non-stock band aid fixes (doublers) that can lessen the effects but once the pans are distorted leaks (seepage) will ensue.

This guy gives new meaning to the Hot Rod terminology words of "woody" and "billet". Definitely worth watching.

Phenomenal!!

The prices are really affordable. They'll probably sell out quickly-even for Cougar stuff.

803 has a MICO and override traction bars.

Gruesome Newsom's perfect utopia. All law abiding, tax paying citizens are fleeing Kommifornia. Let all the whack jobs, illegals, criminals, homeless drug addicts stay. Great job Governor. Another reason not to stay...

Another Reason not to even VISIT.

Just think, 'ole Gruesome is in line for POTUS! I'll bet that the line forms for 2024.

Try Shelby Parts & Restoration for the eye bolts that you need. I bought a complete set (albeit a few years ago) of NOS eye bolts prior to Jim's passing.

Good luck.

I tried implementing the suggestion by S2MS in Post #68 for "ignoring" posts by individuals. I must have done something wrong as our man from Florida's posts keep appearing.

What did I do wrong?

Thanx

Frank

There are many well-thought-out comments that have been submitted in a diplomatic manner. I personally feel that removing member post counts is a disservice to those whom I truly respect and consider the underpinnings of this forum and the technical knowledge/history of all things Shelby. Their post count should be even higher as far as I'm concerned.

On the other hand, I don't appreciate all the clutter (like what's happening in Florida every five minutes) that appears for no other apparent reason than to boost post count. I personally will not even open posts from repeat offenders as they serve no useful purpose, in my opinion. If I've offended a frequent Florida poster with my input, too bad. I chose to NOT be diplomatic with my comment. Sometimes the message gets buried.

I guess that if I were to put an inline filter in a cooling line, I would chose to put it near the transmission where I could hide the "ugly" of such in installation. Personally, I don't believe that at this point in the life of your transmission, that one of these filters is really beneficial.
