Lifter Won't Prime

Correct me if I'm wrong "but isn't moving #7 to #5 a bad idea" ? Maybe not for a short test but then ? I was under the impression once the lifters are broke in they are married to the lobe for life.
I'd take Carl's advice and will do so as soon as the 390 build gets rolling. Carl gave tons of really good (**** as hell) but great advice on preparing and maintaining a motor and is sorely missed as of late.

I agree. Moving #7 lifter to #5 is a bad move. I did this in an attempt to isolate the extraneous variable (oiling problem vs. lifter problem). Now that I have isolated the variable (lifter problem), I can begin trying to find a lifter that will prime up. Today, I went to 2 different autopart stores (NAPA & Autozone) and told the attendant that I would purchase the lifter if it would prime. Within my can of oil and a pushrod, I went through a total of 7 lifters they had on hand that wouldn’t prime. Am I doing something wrong?? I submerged the lifter in oil and then used the pushrod to pump the lifter. NAPA had clevite lifters and Autozone had Melling lifters.

On that note I intends to pre- prime the ones for the 390 just for a look see after this experience of yours. Then I'll tear them down and clean them for installation. Leaving them lightly oiled for preload preparation.

And things were going so well!
My first thought when theis thread started was of Beemernut saying he would disassemble new-from-the-box lifters and clean them in mineral spirits, one at a time. He was pretty surprised at the amount of metal shavings cleaned from a set. He was not surprised not that they were there, but that there was more than expected.
Sounds cheaper than another trip to the auto parts.
I couldn't tell you who carries "Made in USA" brands among the parts chains. I trust Survival Motorsports because it is BarryR's lifeblood, unlike some volume discounters.

Yep Mike, Carls right about that, Its not usually the machine work..But when they go to the deburr deptpartment prior to cleaning and assy..Is were the problem lays....Being a Machinist for years now...the newbie Machinist all start out on the burr bench..and dont really give a ***** about the product as its a boring job...Been there done that...LOL..
And it could be that the Oil metering hole's Missed the ream in the process and left a hanging burr inside the lifter's..Could be a number of thing in that batch....But cleaning them and checking for burrs with a de-burr tool prior to assy is a smart idea..
Any good engine builder worth his or her salt...will take a brand new part thats of the mechanical nature and tear it down and check for toleremces and imperfections... It just safe and cheap insurance... JMO....

Thank you for all the advice. I will disassemble the lifters and check for burrs. Then, I will reassemble and attempt to prime. Also, when I prime the lifters I have them completely submerged in oil. I will let you know what I find.

Update:
I wanted to let everyone that I believe I found the root cause of my lifter problem. Last evening I pulled the intake and discovered that 2 oil galley plugs were missing. Specifically, they are the plugs directly under the intake manifold at the rear of the motor. I now need to find out what size these plugs are and replace them. I am sooo relieved to find this. I have been experiencing low oil pressure (30 psi @ 2000 rpm) and chasing “bad” lifters.
Again, I want to thank Krewat, Redmanbob, Freightrain, Hypoid, Tedybear, and RapidRuss for all their help. I don’t know what I would do without the help of these FE gurus and this forum.

missing ? are you serious ? I wonder if they were actually left out during the rebuild (hard to believe) or they popped out. I mean when you get done assembling the blocks freeze/oil plugs and there are parts left over or come up short.. uuuuuuuuhmmm

I believe they were left out when the block came back from the machine shop. The engine assembler (chevy guy) must have overlooked them. I am just glad to have found the missing plugs.
Redmanbob, do you know what size these plugs are? When I replace the plugs, should I use a sealant?

the ones that came with my kit were pipe plugs. I had to thread the block then install. You could use a punch and a deck screw to remove one of the others and take it down and get three. Hell if your missing to in there that scares the hell outa me LOL Curious which way the cam plug is installed about now ,,,,,,,eishhhh BOL with it.. Glad you spotted it. I'd be contacting the guy on it myself.. he should know what size plugs go in it and obviously have a few laying around LMAO!!

Guru? Me? You have me confused with someone else 
UNIX Guru, maybe... But FE? Bah... Just loads of free time.
Lance, glad you figured it out, and that it didn't cause any damage. Good luck with it, and definitely report back as to how it runs

Now that's what I call an OIL LEAK!!! Wow, surprised it made much oil pressure to begin with? Two 1/4" holes open up top? Mine have always been tapped for pipe plugs, so I can't really give you a heads up on the proper freezeplug style to put in. Not even sure what kind of sealer is used on those type plugs? Maybe a touch of hardening Formagasket?
I suppose your "machine shop" should be able to come up with the proper "kit" for the plugs? Maybe some FREE GASKETS to reassemble it?
Sure glad you figured it out.
GURU huh? Does that come with an increase in pay?? LOL!!!!!

Sealed Power lifters now come from Mexico and are made by Moresa. When I worked at Sealed Power Moresa stuff was considered junk and we would not buy it. Now that anybody who cares is gone junk is considered "OK" as long as it's cheaper. Don't know where Melling gets theirs...
Stanadyne makes a good lifter - but you'll play he!! finding them. I think Comp is using them now, but can't prove it.
I buy lifters from HyLift. Some are reportedly from China. No way to support or deny the rumours. The ones I've been getting are five year old "new old stock" from when HyLift was in Muskegon before a rash of buyouts, etc. These seem pretty good.
