New LS1 Owners - Newbie Tech - What are solid rollers (valveterain)

These two words are used a lot, and i have no clue what they are, and what they do better?

I thought the dealer was buying your car for $50,000 :gay: :bs: :wrist: :thumbsdow :STFU: :givesfuck :supergay: :hump: :swing:

basically they are great for HIGH rpms

the rollers are solid instead of mushy :corn: :suspiciou

Stock hydraulic roller lifters have a plunger of the pushrod end of the lifter. This plunger gets pushed in around .1 inches as the lifter is lifted by the cam. This plunging causes a lot less stress on the valetrain (pushrods, valve springs).

A solid roller lifter set does not have this plunger and every movement of the cam is solidly transfered to the valvetrain, thus is a bit noisier and wears out the valvetrain more as well as requires periodic lash adjustments. Only go solid in a full race car.

means the lifters are not hydrolic for all out racing they are better but not recomended for street use requres lots ov valvtrain adgustments
