I recently ordered a solid f/t cam from custom cams.When I asked Harold for some lifters he said he only had the ones with holes drilled in them and I should really get a set of Johnson or erson lifters. I cant seem to find any. SEC does not even make a solid lifter right now, Go figure. Anyway could you guys point me in the right direction for a good brand and supplier.The cam is about 278 @ 50 and 600 lift for a bbc 468.
:confused::confused::confused:

Some lifters have holes drilled in the face that meets the lobe and some have larger holes in the side groove that rides in the lifter valley and some have no hole at all. Any one want to educate me on what thats all about and how it affects oil pressure ?
:boring:

The holes/groves are designed to better oil the cam/lifters on a flat tappet cam.

Those mods to the lifters will lower the oil pressure a some,not usually a lot but make sure you run the opt higher pressure spring that comes with most bbc oil pumps like the std volume mellings m77 pump or newer the mellings series pumps with those increased oiling design lifters. Running 10w-30 oil will likley result in more oil pressure loss then running 20w-50 oil will with those lifters so keep that in mind too.

Due to the increased/controlled oil leak(for lack of better word) that these type increased oiling lifters cause i am not sure if you need to go with a high volume pump to make up for that ,i would think not for a mild street motor but a race/higher perf motor like you look to be runing with that big cam may need it.

But other more experienced engine builders like MikeWolfplace/BillK/etc can better answer that one.

cstraub has johnson lifters for 150 with the holes drilled. Cost you about 160 shipped.

In my bbc 427, with a standard oil pump I get 25 lbs at idle and 55 psi at rpm. Smidge low with a tight motor imho, but not excessive. SBC are different. Use the heavier pressure spring in the stardard nos Melling pump. It should give you 30-35 at idle and 60 at rpm with a tight spec'd mill. Perfect imho.

Havent checked at 7200 rpm. :D

Fabio, Sounds like you sugest running the lifters w/ hole over the standard. Thats where some of my confusion is. I got the impression the holes were a negative, after further discussion, I think he was just telling me I didn't need them and he had standard Johnson style lifters lasting just as long if not longer.That was leading me toward finding just a good quality solid lifter "old school "stuff. Hope i am not confusing you.

Comp. & Crane have solid lifters, have used them for years with no issues, it was my understanding that Johnson made the lifters for most of the big USA cam companys anyway. Check with Competition Products they carry different brands at a great price.

I sell only std Johnson flat tappets with or without the hole. If it were mine I would run the lifters with the holes.

Same here & I normally have the SEC/Johnson EDM lifters in stock
Email me if I can help
BTW, the Johnson lifters are also lighter than most at about 86gms.

I reckoned that on a popcupine head, street duty ( idling etc) and a precedent of wiping a cam in the same block, I sent my Crane lifters to Crower for the hole. CHeap insurance imho, but Mr. Brookshire did say it was likely unneccesary. I wish I had used the heavier spring in teh Melling pump is all.

I would run the ones with the holes, consider the lack of quality oil and the spring pressure on a bbc it's cheap insurance.

I run the EDM hole solid lifters on my solid ft Lunati 401A6Lun without reservation. It does drop the oil pressure initially, but I regained it by going with a heavier oil.

I'm running the Isky edm lifters. I run approx 150 lbs seat pressure. I'm using the moroso blue print standard volume pump with the pink spring from the melling high volume pump. There was a time when you could get these springs from melling but they got really stingy and lost their sense for proper customer service and customer satifaction. Another American company who has lost it's way... When hot, the thing idle's in gear at about forty lbs and is at sixty plus over 2000 rpm's and at 70 lbs upwards from there

A heavier spring will have no affect at all on oil pressure at idle. That relief valve spring only controls the max oil pressure that can be reached. A stiffer spring will not bleed off until its pressure is achieved, which would be at higher rpm. Its quite conceivable that you could change to the higher spring and see no difference at all in oil pressure, if your pump and engine internal bleed off are such that you never reach relief valve pressure to begin with. If you are concerned about uping the pressure all the way down to idle, then a high volume pump would be in order. Then you could decide if you needed the higher max pressure that a stiffer spring would allow.

Hope you have the older Moroso "blueprint" pump
The new ones are a joke, they are based on the new light Melling casting which has shown a tendency to depart from the rear main on occasion.

Could not agree more about Melling, they seem to have their collective heads up their corporate ass's :mad:
They still have great technical support in the form of George there &
you will find if you call & talk to him he will go out of his way to do what he can for you.
But apparently engineering has no say in what goes into the damn box anymore.
Seems there is a lot of this going around of late :sad:

On a lighter note,,,
The New Melling pump is pretty nice, very heavy casting, good pricing.
Hopefully they have corrected the spring screw-up with the first batch I don't know as I have not received my new order yet
I sent all of the first standard volume SB ones back for a low pressure issue & it seems they had the wrong spring installed.
This does not apply to the HV ones, they are fine if you like HV pumps.

Mike do you order a couple hundred of these at a time like GOFAST does???

No,, I am not important enough to get that many :pout:

But I did get a whole big box of valve locks the other day,, :D

BTW, do you do any 348/409 stuff at all?
Wrote a program last week to probe, bore & deck them, hollar if you want it ;)

Thanks for the heads up on the pump. I've had this one in service for a couple years and so far no issues. I did'nt know for sure this was a melling casting but thought it likely. I was also not aware of the powdered metal gears until recently either. I emailed melling and was told that this was being addressed. I hope so. Bean counters should be limited to counting beans, Jelly Beans!!!!!

Thanks Mike as I will keep that in mind
