Solid Roller Cam ??

I remember when CC first came wout with beehive springs for the SBC. And I remember reading about some failures. I used them for a while, but didn't see any real differance. I'v also heard the argument that dual springs can support the valve if one of them breaks.

That's something I'll be watching as the years go by. I'm tempted to be bold and try them again. But that can get expensive real fast.

Not trying to beat a dead horse, but trying to understand a little better. I have no experiance with solid lifters at all.

Lash is - essentially - a bad thing. It makes the cam "smaller" when you really want it to be bigger, and causes parts to bash together. Which is why solid lifters and cams don't last 100K miles. Launching the lifter off the back side of the cam lobe can't be a good thing. Wasn't that the reason hydraulic lifters were invented - to prevent the bashing, and therefore make things last longer?

So, if you want lash to be at it a minimum during the worst/harshest operating range, why would you not set it at something like .001" cold, and let things grow as they may? The cam would not shrink, and things wouldn't bash so much. Why start out with such a big lash?

Again, not trying to beat a dead horse. But I like to understand things before I give them a try.
