The hyd will act sort of like a plunger the solids dont move

................there will be a wire clip holding in the plunger on a hyd lifter.......solids are like there name implies, no plunger just the pushrod seat....kim........

cool thanks, and what about the cam? id say its stock, but the motor looks rebuilt so i have no clue if it was changed (just bought the motor second hand)

its fine to run hyd. lifters with either a flat tappet or roller cam as long as its a hydraulic cam right?

ok, these are the exact lifters i have. what kind of cam is needed with these lifters? any hydraulic cam?

a flat tappet cam (either solid or hydraulic) uses different style lifter vs a roller cam (either solid or hydraulic).

So the lifters i have can only be used on flat tappet hydraulic cams??

Those lifters sure are expensive no? Especially for your set up. These would work fine at less than 1/2 of what those cost.

These are 1/4th the cost......

Careful guys. Some solids do indeed have a plunger. The difference is they do not have any spring resistance for preload. Some solids out there you cannot tell the difference looking at them from a hydraulic. Easiest thing to do is remove the snap ring or wire clip from one and take it apart. If is has a spring and plunger, it is hydraulic. Just a plunger with no spring, it is solid. Of course if it is a solid chunk of steel then it's obvious.

i know theyre pricey, but im not trying to buy them I already have a brand new set of 16 lol. i just want to know what kind of cam i need to run with them. They came with a 318 i bought but i have no clue what kind of cam i need to run with it. Im guessing a hydraulic flat tappet? since theyre "tappet" lifters??

Yes, those lifters are for a hydraulic flat tappet camshaft.
