I wouldnt even touch a set of adjustable rockers until they are needed. Stick with a hydraulic roller and use custom pushrods, then worry about the adjustable when you are making that big power number...
The LX cars have been making big hp for awhile with strokers and no adjustable rockers, I would wait for the aftermarket to catch up and hold out. Thats what I am going to do...
Few questions for the Gen III experts. Sorry if these are rudimentary and covered elsewhere...:
- How much lift can the stock rockers handle?
- How much spring can the stock rockers handle?
- At what point do the stock rockers become unsuitable, a liability, and/or unstable?
- Can you sufficiently cam the engine to use the higher lift flow that is available and still use the stock rockers?
- Can the stock rockers handle .600+ lift?
The stock valve springs are 98#'s @1.77 (closed), and 242#'s @ 1.28 (open). Yes, the stock rockers and handle .600+ lift, many guys have been doing it for a long time. Manley makes direct replacment springs that will handle up to .650 and there are many companys out there making cams that will use all that lift.
