    Anyone able to ID these bb Mopar mech roller lifters . Brand new in box but no manufacturer or part #. .750 roller size !! I notice there is no oil feed hole either . The old guy I got them from said he bought them for his 440 . Never used them. He had a computer invoice for them . The invoice was really faded couldn’t tell anything about place bought or part #.

    That looks like a Herbert lifter. I don't know where Herbert got his lifters from, so they could be the same lifter in a different box.

    That would be the perfect lifter for a nice hydraulic roller lobe. Set the lash at .0015-.0020 cold and run it.

      Is the hydraulic roller lobe ramp not as aggressive as to a mech roller lobe ??

      Looks just like the Herbert lifters I had in the 90’s.
      I used them with a .650 Ultra Dyne roller for 3 seasons of bracket racing(no street use).
      I’d be okay with using them on a milder lobe on the street...... I just wouldn’t leave them in for too many miles.
