The official FABO machinist/member collaboration, busted 340 thread

I'm hearing that new lifters aren't cutting the mustard. Is this the only option these days?

Wonder what is causing failures, assuming correct methods are used for installation, along with coating all surfaces with a break-in lube typically supplied with cam & lifters? Metallurgy?

Interesting, what do you do to update internals?

Good stuff here folks:thumbsup:

The reason we used the older lifters, is they were nearly new in the early 80s, ran only a short time, so by using them, we know we have better metallurgy than the china ones available currently. We will disassemble and inspect/clean internally, but I think our chances are pretty good!
