So, I have to know........ (solid vs hyd)

hydraulic lift motor cant rev like a solid lift motor and hydraulic lift is less fynicky. not all hydraulic lift cams need adjustable rocker arms either, it just depends on how wild you get with cam selection. theres nothing wrong with hydraulic lift, their obviously great for the street and can provide good power. In a nutshell it comes down to how many rpm you want to turn and how much matinence you want to do/not do.
