A lot of variables here .
Ramp design, valve weight, spring pressure, Rpm, to name a few.
Cast iron cams with aggressive " Stocker" Ramps , tool steel lifters with 215/400 maybe 100 runs before there's lobe issues and need to be replaced.
More spring pressure , fewer runs, less spring pressure more runs.
Tool steel cam cores, DCL lifters , can run higher spring pressures , no break in issues.
PPPC in NC make a very good DCL lifter
Coating work done in France. Delivery sometimes can be longer than you want. Around 1,250.00 a set.
