Is tha cam saver groove in the lifter a good Idea for a 215?
Tony, got a pic ? EDM hole, for mechanical, works. What's the sales pitch ? roverman.

CAMSAVER HYDRAULIC LIFTERS
The maximum in cam lobe and lifter life.
If high spring pressures or extreme and
unusual operating conditions have you
worried about lobe scuff and lifter wear,
insist on Crower "high-lube" CamSaver
lifters. These lifters deliver 20% to 30%
more oil to your lobe and lifter faces
for the best possible insurance against
premature lobe and lifter failure. Specially
machined flats put 12 to 16 ounces
of additional oil per minute at each lobe
without adversely affecting engine oil
pressure (nominal drop of just 1 or 2
pounds). Crower CamSaver lifters incorporate
the same precision ground radius
face and finish as our standard lifters to
insure quick break-in and trouble
free operation.

I like EDM hole = fast bleed-down hydraulic.
The EDMs were only available for solids. this is thier solution for hydraulics I guess... They say it only lowers oil pressure 2-3LBs and after mulling it over I figured it couldnt hurt. I wont be high winding this engine so I wont worry about a little additional windage raining down on the rotating mass.
More importantly, who among us checks the actual lifter to bore clearances ? Perhaps more important than a small flat, on the lifter ? I suspect excessive bleed-off, on the primary feed lifter bank, to be problematic. roverman.
Good point on the lifter bores!
They state only a 2-3 lb pressure loss...Have a high volume pump and adjustable pressure regulator. I guess if that cant keep up the lifters are going back.
