really well known -- In some circles , comp lifters were junk for about two years maybe about 7 years back -- they went off shore .I forget the timing exactly They vigorously denied doing this, blamed oil , break in , process etc etc . Just Follow the $ My friend is a lifelong engine builder , a true pro, 3 man shop , full machining etc he has built 1000 plus engines, including coyotes with .700 lift ... And many stroked hemi etc , 3 engines for me . He has a seven second street camero , blown etc . Nuff said One summer in the past , he had to EAT a dozen 20,000 $ race engines , almost broke him financially . Honest guy , -- he made it right Big had the fight with comp, over the wiped lifters story . They said oil , zddp fairy story etc all BS. He told them he has used 4-5 55 gallon drums of stockpiled oil , same the past , same oil, 3 years .Before and after this And after . He bought it in bulk Next ? Zero problems , never any issues suddenly lots of problems , zero failures prior He had some lifters before episode (during and after ) on shelf , he examined w microscope , noticed totally different machining marks He had them checked at lab ,-- different heat treat . He settled with them . Cannot tell any more -- confidential -- but he went elsewhere on lifters And problems were gone . Cams apparently were still made probably ok . But lifters hurt them Not sure of all the intrigue Coincidentally I was building a stroked 392 , ( 450") he did all the machining . Lots of it . (an Ex dragster billet crank) , Mallory metal , aftermarket chev smaller rod journals etc to balance , etc I had decided ( at the time), I liked I liked the story of (? Howards?) lifters , with . the approx .015 hole in the center of cam face ( solids) . Went that way . Car still not finished , but I saw that those have doubled in price --big money now. must work , 5 years +on ... waiverd around a bit on that , but went with it Not current on all this today-- but heads up . Your story of ? wiped ? lifter yet done in . but cam " not destroyed " may sort of flits this . Why i bring it up was how vehemently they stuck to the " Story" --- when the story was obvious bullshit from the story . And it stopped happening , same oil , cam etc . with used with other lifters Draw your own conclusions , I did I feel a I accidentally dodged a bullet I soon put in aftermarket roller lifters in on a 440 hydraulic . No problem , not loving them , but was afraid of snuck in flat tappets from Asia . Yet flat are / were ok on millions of 440s , all probably real mopar, made in usa etc Nothing normal done ,just thrown in used by the millions across 25 years . Probably ok now.. Maybe Mancini etc may have good stuff , just detour around this . Why bother with a dance .. not worth the aggravation , will never get to bottom . Hard coat is thin on cam if it is hurt you need both imho jkg On May 21, 2026, at 10:39 PM, Robert Hayen <rbrthayen@xxxxxxxxx> wrote: -- For archives go to http://www.forwardlook.net/300-archive/search.htm#querylang --- You received this message because you are subscribed to the Google Groups "Chrysler 300 Club International" group.
