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.

I don't baby anything I own and my 340 is hyd roller setup. Plus it really depends on what you're doing with the car and if it's a stick or auto. Mines an auto so sticking a solid and revving it to 9000 Rpms is pointless when the auto limits how high you can go. Plus I dont have adjust my valve train all the time.
