Does anyone know the max lift for the dumb bell style solid lift before you uncover the lifter galley oil feed? I know that doesn't happen with the full body solid lifters of course, but I am in process of putting an Isky E4 cam (.425 lift) into a healthy 318 build and have a new set of the 2084 solids.
Thank you in advance FABO!
 
Thank you That's what I remember as well just could'nt find it online
I know years ago they had the tube and peen kit to override that issue with +.500 lift cams and those style lifters
 
Get a slant 6. Then you can run a .750 roller and it won't matter.
 
Yes, I gues you could do a regrind or ask for a small base circle cam... but spending extra money just to work around a dumbbell lifter seems kind of dumb
is it possible for a too small a base circle cam to drop the grove out the bottom of the lifter bore creating same problem on the low side???
 
With flat tappet lifters?

Yeah, with dumbell lifters. The point I'm makin is that dumbell lifters in a slant 6 won't uncover any oil passages. You can leave one OUT and not lose oil pressure.

the base circle gets dropped. The tappet lift compared to the bore does not change much as the cam lobe tips barely clear the bearings as is even on a dog pie stocker cam. .490 max? if the MP book says so....of course it could be wrong....;-)
 
Well, on my next build, I'm going with .550 lift, so I'm not taking chances. I'm going to run big block solid lifters. With EDM holes.

Was not aware of a "big block solid lifter", got a P/N or a link? Please
I do like the idea of EDM holes
 
someone checked the dumbells on a .650 lift cam...if you can decode what he's laying down. 'Bullet' lifter was the Mopar/Johnson dumbbell design.

so at zero lift (lifter deepest in the bore on the dropped floor base circle) the oil band was still not exposed. At full lift this doesnt seem to matter as i said earlier, the relative lift of the tappet off the edge of the bore does not change much. The Howards lifter was 22g heavier than the 100g dumbbell and the hollow full body MP solid lifter was even lighter at 90 without oil. Not my data.....put 2 lifters in and dry cycle the cam. if the band gets exposed on the base circle (most likely on the cam side) , you've exceeded the lift range of the dumbbell lifter. My dollar says no way on a <.650 @ valve cam.

This is actually the first I've ever seen a figure on it. All I've read or heard was they "might" uncover the oil band.
 
PAW used to sell those in a Milodon box, and they were marketed as “light weight” lifters.
It sounded good to me......and in the mid-80’s I tried them on a Racer Brown STX-19(.530 lift) in a 440 block.
That was my first solid lifter cam.
Oil pressure gauge barely came up off the peg.

I swapped to some of the normal smooth sided lifters...... oil pressure restored.
I never tried them again.
 
interesting...wonder what the root issue was. That data was on an RB....
@RustyRatRod and they all erroneously claim that at full lift too.

Were they too low in the bores or did they travel too high? Inquiring minds wanna know.

I have seen that some solid lifters providers state that they have moved the oiling band down to avoid the band being exposed.

Also too, another point a lot of people don't realize is small and big block lifters are not the same.....even though some vendors advertise them as such. The oil bands are in different places....AND the big block has TWO different styles. One I think is like 66 and back and the other 67 and forward....I believe that's the split. So there are THREE different styles for the V8. That gets over looked and sometimes can cause some grief.
