Lifters solid or hydraulic roller?
I started motor for the first time on Sunday. We put in a solid roller. Problem is I think I may have been given hydraulic roller lifters instead of solid. From what I understand you can't visually tell the difference between solid/hydraulic roller lifters. We have adjusted lash multiple times and from what I understand is that with a solid I shouldn't be able to move the rocker/pushrod. You can push on the rocker and the pushrod goes in a hair (see YouTube link) a solid roller shouldn't do that should it?

Re: Lifters solid or hydraulic roller?
OP,
I learned the hard way on my 496 build that you can not use cheap Chinese (ebay) hydraulic lifters, because the springs collapse too easily and won't hold lash.
If you have a cam designed for solid lifters run solid lifters and the same goes for a hydraulic roller cam.
Good luck and please keep us posted.

Re: Lifters solid or hydraulic roller?
I thought they were solid lifters for my solid cam, but I don't think if they truly are solid lifters they should be moving down a tad. Anyone ever have solid lifters that did that?

1. You set the valve lash with the engine cold?
2. Your youtube video shows you pushing on the rocker with the engine cold?
If the answer to both of these questions is "yes", then I believe what you're seeing in the video is normal.

Take 1 apart. If it's a solid, it will not have the "pump".
Hydraulic on left - Solid on right.

Re: Lifters solid or hydraulic roller?
Ok I got it back apart and I am pretty sure the lifters are solid. What I now think is happening to make it have that movement is possibly the pushrod is a tad to short. It is a 383 stroker with a small base circle of .900. From what I understand is with the smaller base circle you need longer pushrods. Mine are currently 8.250. I'm thinking I may need 850's. Pushrod just seems like it's not keeping the roller on the base circle. Opinions?

If that is true, then STOP! If that lifter rotates in the bore, the camshaft at least will be trashed. You MUST have valvetrain geometry issues. STOP and make it right before continuing.

Re: Lifters solid or hydraulic roller?
Oh I already have stopped and I working to fix the issue. I will also be pulling cam and going smaller. I had the right torque converter, but it's bad and I can't use it. So now I have to use the 3000 stall converter and will need to swap cams. As far as the lifter issue I'm still working on that. I don't think I could go with a bigger pushrod with this high lift cam anyways. Not without getting spring binding and I don't want that either. I will go over everything when I call about a cam and see what they come up with as far as the lifter issue.

Re: Lifters solid or hydraulic roller?
I double checked pushrod length and they are good. I did put a call in to Crane to see why lifters had that play and I guess they are supposed to be like that.
"An added benefit of the spring-loaded horizontal guide bar setup is the ability to change cams without intake manifold removal (providing a "rev kit" is not used) - it is great for dyno and on track testing"
this is what they replied back to my email I sent to Crane.
"Hello,
Yes, the lifter is held off of the camshaft by the spring until lift.
Thanks."
