Hydraulic Lifter - Is there to manually pump it up?
I am going to be installing a set of Morel lifters when I put on my Dart heads. I have read here that the pushrod cup sits higher from the roller than the stock lifters so it will be necessary to also change pushrods. I want to do a swipe test with checking springs.
Is there a way to fill the hydraulic lifter so that the plunger won't deflect during the swipe test? I am wondering if I submerge it in oil if I can operate the plunger and pump up the lifter. With a dial indicator on the valve I should be able to tell if I am getting full lift.

Use a "trigger-pump" oil can to pre-oil the lifter. Soaking lifters is hit or miss. I don't know about Morel lifters, but the stock lifters bleed down quickly. Be ready to do your swipe test asap and to take your measurements on the first revolution.
I messed with measuring lift at the valves to verify rocker ratios. I was surprised to see how quickly the lifters bleed. I was able to crank the engine over a few times to pump them up again.

Not sure I follow the procedure to pump up the lifter
