So, I've not been successful finding "Who made Mopar Performance Hydraulic Roller Lifters P5249862 for Mopar Perf?" Pretty sure MP did not make these. I'm looking to build a 1990' 360 LA roller block 408" with hydraulic roller cam/lifters. Want to retain factory Spider and Dog-bone guides.
Thanks, TED

Well ... that could have been Federal Mogul/ sealed power.
Johnson at one point iirr manufactured the hyd lifters 'non roller'.
If this helps you in any way in your build I will let you know that I bought a brand new set and used them with 585 lift Factory dog bones and spider. I believe they were sealed power and only cost around $120 or $140 bucks
