At What Point is a Solid Cam Better Than a Hydraulic Cam??

My last 3 cams were Engle Racing Cams in Cali.
All 3 were custim.grinds. one hydrolic flat rapper. Next 2 were tight lash solid.
As variation of KV2 and KV3 together with a fast rate lift and tight last.
Ground to aspects for my 340 stoker
