Money vs Horsepower

You can Revv the engine cleaner to higher RPM with a Solid grind without worrying about lifter collapse and Valve Float. I go Solid on everything cause I like to Revvv em' up! Whether a Flat Tappet or Roller! You wanna baby your set up go with a Hydraulic.

I have broke in quite a few engines with Solid Flat Tappet Cams & absolutely no failure.
