Rollers prevent user error? Nifty stuff

The Crower lifters that went bad, was entirely due to user error. I initially set the valve lash completely wrong and ran them that way for about 20 minutes. Even after correctly setting them, I still did not realize my previous error.

Now I have to measure each lobe to see if the cam is still good...but I am fairly sure it is not, just by the sound.

On the bright side, I have an Isky 280 mega cam and a Comp 290b-6 solid cam on the shelf to choose from. Either should be a significant performance improvement over the 60919.

From now on I will be setting my initial valve lash with the valley pan off. Lesson learned the hard way.

Good article here on flat tappet lifters, how they're intended to work, and pitfalls to trying to use todays parts, with todays oils.
