To answer some of the curiosity.....i have about 6500 miles on the cam and lifters. .670 lift 251lbs at the seat...they were of course comp cams...and they do pressure feed
oil to the roller. i had planned to change them out after this season.
Rick, keeping my reply short....KC built this motor and dynoed it in 2006.
i have plenty of
oil pressure at idle 80+, it is his custom grind....grooving the lifter bores is bad news for a hydraulic block. the
oil pressure drop would kill the motor. honestly Rick i'm not a newbie to the FE. been there done that since 1976.......roller lifter failure does not occur at the contact point but rather in the needle bearings the roller rides on. lucas oil additive is a band aid for bad oil. use good oil and its not needed. 6500 miles isn't unusual for roller lifters....especially comp cams....hehehehe.
what really rubs me....is a little voice told me to change the lifters last year when i re-did the intake gasket........i had a 1980's flashback of soft cams from comp the cams were dropping like flies.......should have listened to myself.....
in any event until i tear it down its all conjecture at best....i may be fine on the cam.....at least thats what i tell myself so i don't freak out yet......
but i do know that i will be using either crower or isky for my lifters.
i am oiling thru the pushrods so the choice of type of cam is limited.
i will probably put another solid roller in
