350, and I do the install. I want the adjustable so I don't have to mess around getting the lifter preload set correctly. I want full lift and full duration on every valve.
This is a fresh rebuilt 318,not running yet. All drive train is newly rebuilt.
I was going to just freshen up the engine but that didn't work out. When doing so, I ran into the problem of lack of preload on the lifters,all of them needing different length pushrods,what a pain in the ***.
Getting a set of used rockers is what I already have, buying another set doesn't make much sense unless they are in very good condition.
If I could find some that are in good condition,verified,I would likely just buy them and be done with this part.
