Roller CAM -FE

[Excaliber]

Special Note: Solid roller lifters are designed for use in racing applications; however if used in street applications precautions should be taken to avoid excessive idling and certain engine builder modifications are required. Low RPM usage may result in a lack of lubrication from windage, premature wear and ultimately extensive engine damage.

Well that pretty much says it all right there. There have been no significant advances with "long life" in the solid roller category. Same now as it was years ago, use on the street as your own risk.

...your left with the "I like solids!" argument without any other reason than "it sounds cool."

You left out the WAY LESS expensive part of the argument. You can do a flat tappet for a fraction of the cost of a real quality hydraulic setup. For some of us, THAT is a very valid reason indeed!
