Hydraulic Followers best?
 

which are the best hyd followers for a bbc gen 6 ? my builder told me Jesel but they dont do hyd once apparently

any one ?

Morels.crane.comp cans.howards and the Johnsons
All good lifters
Just make sure the clearances are in check

If it is under.580 lift, factory GM.....

Doesn't Morel make the GMPP lifters?

Pretty sure Johnson makes GM's.

For what its worth Teague uses Johnson and tells me they are the best. Teague used Johnson short travel, oil hole in my 1250 rebuilds.

I am using the factory GM's at .625 lift with no issues. 170hrs now and still going strong

I have 632 lift

Are these Rollers? Proper spring pressure is a big factor on how long they live. If the roller is allowed to leave the Cam Lobe at any point then the life expectancy is greatly reduced...

yes, and that problem can be exaggerated, when the cam lobe lift is too much for the duration. The fix for that, is adding much higher spring pressures, to keep the lifter on the lobe. But then, too much spring pressure, is also not good for longevity.

Johnson uses a .700 wheel, morels use .750, and some larger diameter body lifters, even bigger. You should talk to your cam company/grinder, and ask what lifter wheel diameter, the camshaft was designed for.

Is this a good time to bring up the subject of oil and oiling too ? Uh, oh.
