They are a retrofit hydraulic roller from hughes engines, might have been made by comp cams at the time, which looking at my invoice was back in 9/29/2006. most of the hughes part numbers on my invoice doesn't even come up on their site.
Fuckin 12 years ago, and here I am finally starting this engine up as of last month. Whether they forgot a plug, jacked up the main bearing clearances, or these lifters I have are just straight up junk, I don't think Hughes would be willing to help.
I guess I *COULD* maybe try those 'drop in' no mod necessary solid roller lifters from IMM, or the other guy who out of business, MRL? Think they are BAM is the name? I dunno.
