The GM Performance lifters with the stock dog bones should handle that cam with no issues. I’m no engine builder but got the blessings from top builders that the GM stuff works great on my .610/,627 cam.
When i installed everything the lifter was still flush with the top of the dog bone bottomed out and still had about 3/32” left before lifting the dog bone.

I can’t find any part number for the lifters I’m using, and this is the closest I can find but have no idea if they’re the same ones I have. I’ve spun mine up to 5800 for a short time with no issues.

I'm looking into options for hyd roller lifters...what's everyone using?
cam...
278/288
.612/.618 lift
114 lobe separation
5500ish rpm...don't plan to spin it any harder than that
I do need the tiebar lifters so let's talk specifically about those please
Reason I'm looking long story short is I'm getting a tick in my freshly rebuilt motor and I think I have it narrowed down to a lifter either failing or just wore out not sure. They are comps that are in it and I think it's time to upgrade to something better.

As far as I know, many have been using the Johnson lifters, as Teague, Eddy Young, Isky, and others have been using/selling/etc instead of the Morels they all used to.

Well I reset lash on all the valves and it did help drastically but if you are very close to the engine listening for it you can hear a very very slight tick....At this point I have bigger problems so this issue will go on the back burner till the other issues are resolved...thanks for the info everyone!!

Took them down to zero lash by feeling pushrod/rotating it/moving up and down etc. then tightened the rocker arm another 3/4 of a turn. They were set at 1/2 turn from what I could tell so I went a little more just to make sure they weren't too loose. This was at the guidance of the engine builder...I have lost faith in them however I'm not made of money and they told me that if I did this the way they want me to then they will still warranty it.
