lifters
I recently ordered GM # 1249925 lifters for my 93 Z28.
I was sent a AC Delco # HL 124./With a GM #17122490 on the box. Are these the same?
Has anyone had this problem with, possibly, 'bait and switch'?
Thanks for any help that I can get with this problem.

Re: lifters
I'd say that you got the correct lifters.....seing that AC Delco makes many of the OEM GM parts in our cars .....

Re: lifters
Finally got the answer. The # 1712290 is for an individual lifter from the set of 16 lifters #12499225.
Thanks for the suggestions /answers to my problem.
But.. what is the adjustment/preload on them?
Anyone?

Re: lifters
Half a turn past zero, then leave it alone. Try the oil holes facing forward since it doesn't matter. Then observe which ones get oil first on the first cold start with valve covers removed.
