So I figured out the Iron Duke hyd. roller lifter is just like all of the other factory Chevy hyd. roller cam stuff. The part number I have is a Sealed Power number HT2148. That cross references to pretty much all of Chevy's OEM roller cam engines and any other GM motors that are "Chevy Gen I" motors. Whatever that means. Trouble is, these motors use an OEM tie bar or hold down and don't have provision to mount a link bar on them. So like I say, maybe this is old hat. Sorry if it is.
