Also, Comp Cams makes a Street solid roller, and it's tight lash and real easy on parts. I have known guys to get 30k miles out of them and lifters were still good. Joe Sherman has said he has experienced more failures with Hyd Roller cams than ever a Street solid roller. He went on to say the Solid Roller easily makes 50hp or more with the right Combo.
Hyd Rollers fail also, believe me i have seen them, and valve float at High RPM's with Hyd rollers are common.
Don't fear the Street Solid Roller. My little pump gas 393 has an XR292R Comp Street solid roller and runs flawless, plus car makes almost 480wheel all motor street car man with an EDDY 800 vac sec Carb. No fu#king way is any Hyd roller gonna make that power in my engine with my Combo, no way man.
Valve lash every 1500miles and you are good to go.
Of course a panzy Hyd roller will last longer, but it won't make the power or have the throttle response of a Good Street Solid Roller.
Now if you go with a full Drag Roller then they won't last long. The guy with the red 65 Stang had a needle bearing come apart after 650 passes, but he was running a full on Drag racing Roller cam with huge spring pressures and really aggressive ramps and big lash..
