The Stovebolt Site Forums The Shop Area Engine Shop Is this mechanical or hydraulic 235 lifter?

Hi Dave, looping back on this, apologies it's been a while I have been working on the brake system - did you say there was enough visual in the photo to ID these lifters as Hydraulic?
Lifters

Or should I try and pull one of the Lifters completely out of the block for closer examination? The block is a 235ci, Mfg date of May 25th 1962.

Thanks!
