Sam (Bones) Posted March 26, 2008 Share Posted March 26, 2008 if it is a hydraulic roller....adjust them the same, I would consider going with a solid roller over a hydraulic Link to comment Share on other sites More sharing options...
monte70car Posted March 26, 2008 Author Share Posted March 26, 2008 its mainly goin to be used in a street car. with a solid roller dont u have to adjust the valves after so many hours? Link to comment Share on other sites More sharing options...
Sam (Bones) Posted March 26, 2008 Share Posted March 26, 2008 once you get them set correctly it will be fine, after that...check them once or twice a year I won't use a hydraulic cam again unless I'm doing a factory stock rebuild, I am just feed up with hydraulic lifters (flat or roller) Link to comment Share on other sites More sharing options...

kc8oye Posted March 26, 2008 Share Posted March 26, 2008 what's so bad about hydruallic lifters sam? Link to comment Share on other sites More sharing options...
Heckeng Posted March 26, 2008 Share Posted March 26, 2008 They are heavy, and absorb a little of the lift compared to solids. I personally like them, sorry Sam! I know there are some people who have bashed them in the past--not Sam by the way , but they really are great for the street in my opinion. You just can't plan on revving the engine much above 6000-6500 rpm because they are so heavy and cause the valves to float earlier than a solid roller, but you probably won't do on a street car anyway. I like them because they allow decent lift and quick ramps while keeping down some of the "harshness" that a solid roller will exert on the cam/lifters. They are easier on the valve trane as well, and have less friction, and no lobes flattening out. You should get good name parts though, don't skimp on the lifters. If you have a roller on a lifter go bad, solid OR hydraulic, you are hosed as the cam will be trashed. Link to comment Share on other sites More sharing options...
Sam (Bones) Posted March 27, 2008 Share Posted March 27, 2008 I don't like them because of the failure rate of them, todays quality of them is only so-so, hydraulics have cost me TWO engines Link to comment Share on other sites More sharing options...
Dans '70 Z20 Posted March 27, 2008 Share Posted March 27, 2008 I just converted to a hyd/roller on my 454 to avoid some of the issues surrounding lower phosphorus/zinc levels in commercial oils. Have seen to many cams with really pre mature wear do to this issue and quality issues of flat tappet cams and lifters. My builder and a well known speed shop (S&K Speed) on Long Island highly recommended the Crower Hydraulic lifters. They both said they are the only ones they have seen that do not lose pump-up over time which effects overall lift. To finish out conversion went with crower stainless steel roller rockers and cam to avoid any warranty issues in the future. This way each manufacturer does not blame others part. Stuck with Crower throughout. Thought I would share recommendations I received. Dan Link to comment Share on other sites More sharing options...
kc8oye Posted March 27, 2008 Share Posted March 27, 2008 oh i agree.. roller all the way.. but I guess I've been lucky with hydrallic lifters *shrug*.. but like scott says, my cam can't breathe past 6000 rpm anyway.. (5800 is about the limit of any usuable power) so its a non issue my next cam upgrade, I'm going to full roller lifter, maybe solid, I dont' know yet..
