Solid Roller Lifters on a Hydraulic Roller Cam?

Bewy said

And one of the smartest guys in the industry did not say to aim for zero HOT lash......
What he said was to set zero lash COLD.....& then when the engine heats up, because of thermal expansion, the lash will be 0.002-3". He also doesn't say how you measure zero lash, maybe using the illusionary 0.000" feeler gauge. This is important when you only have 0.002" hot lash.
While I have great respect for Steve Brule, he has given bad advice.....
Hyd cam systems self adjust/compensate for any wear. Sol lifter cams have no compensating, other than the lash. 0.002" lash at operating temp as a starting point is asking for trouble.....

Once again I am speaking theoretically Bewy. Because of the lack of a clearance ramp the perfect scenario is zero lash hot. Even though we know it won’t work there. It’s a point made to show that a hydraulic roller lobe with a solid roller lifter on it will work best and not beat itself or the wheel up when there is no lash. Brule was not passing on bad info and neither am I. When cold set to zero lash (and on mine I use a very light zero lash) and with my iron heads, I see .002-.004 when hot. It’s hard to get a good measurement with feeler gauges that thin. And once again mine has been running this way for LOTS of miles. You do you, I’ll keep doing me and saying here what has worked in my experience.
