Somewhere about 60K to 70K miles the lifters will get noisy in any engine due to wear, dirt etc. Especialy of the pre-1980's era. Replace the lifters????? WHY??? because they are worn???? They usualy wear at the base that rubs the cam. On the engines with adjustable push rods or rockers one can simply give the adjuster nut a quick 1/4 turn and noise problem solved for another 20k to 30k miles until the bottom of the lifter wears thru.

It's not like Packard was offering engines for the commoners of the world. They were supposed to be offering quality, long life and service.

Build a new or newly rebuilt engine and ship it out with a 3 year or 30K mile warranty is one thing. Run one 150K miles and squeeze another 50k out it is another.
