Gday
currently building 350 chev for my hq.
Am being pushed by different people to go for different lifters.
Solid or hydrolic ?
Have roller cam with big lift.
Am worried hydrolic may cause h/p loss but have been told solid needs constant ajustment.
Advice much appreciated .
Thanks

Hi micka
If you already own the cam, the decision is already made for you. The profile is machined to suit a specified lifter. You can't change from solid to hydraulic (or vice versa) without also changing the cam.
To answer your question, hydraulic |

Doc, I would not entirely agree with the profile for a lifter argument. The roller vs. flat lifter cant be changed (as the cam lobes are shaped differently).
If the cam has been used before (especially a flat-lifter cam) then the lifters should stay w |

A cams profile is made pacifically for solid lifters, or hyd. not both. you can but it would be a foolish thing to do.

I'm with Rosenberg on this one. I've never seen a camshaft machined so that it could be used with either type of lifter.
AFAIK the ramps on a hydraulic cam are differently profiled to allow the hydraulic lifters to function correctly, while the solid |

I stand corrected. When I was researching with the Comp CAMS, they offered their CAMS with either solid or hydraulic in each grind, but the roller vs. flat could not be interchanged. The cams for roller lifters were flat surfaced, where those for flat li |
