I am in process of having a shop freshen up a 62 235 with reground crank, pistons, etc. and the subject of a cam choice came up. I was planning on a moderate hydraulic cam but noticed in Patrick's latest catalog, that hydraulics are not available. The reason stated is that Patrick knows of NO satisfactory hydraulic lifters in current production. As such, only solid cams and lifters are offered. Has anyone run into this situation? I really want the hydraulic experience. Thanks in advance for replying.
