shimming hydraulic roller lifters solid

mderoy340 said
I've disassembled my SFT EDM lifters and it is an empty hyd lifter with the DDM hole on the face. Lifter body, cup, and snap ring. The OEM hyd roller needle bearings are splashed oil as far as I can tell. I'm not sure how they would hold up with a solid roller. A tight lash SR might work. I'm on the fence about sticking with a SFT/EDM lifter or spending the big bucks for a SR setup on my street strip motor.

If they are the same as a hydraulic, then what's to stop it from trying to pump up? Is removing the disc valve all it takes? That's what I've been getting at. That's why I don't think the idea to shim them solid is a good one. If the lifter continues to try to pump up, then surely sooner or later it will pop the wire clip out and come apart. The pump up part of the hydraulic lifter must be defeated.
