Should be an 8 digit GM part# on them SOMEWHERE.  Call up a dealer with them and see if they can answer the question

The size is dependent on fuel pressure, AFAIK each mfgr uses different pressures...

4.6L 32V Mark VIIIs and Continentals are a good source of 24lb injectors. Also 460 EFI trucks have 24s.

I'm still looking for them.There just aren't any of those cars around here right now.Usually they don't charge me for injectors,that's why I don't want to buy any from Ebay or wherever.I figure I'll be patient an some will show up eventually.

Yards around here are up to $6 per injector. Needless to say, unless I come across some 35#
browntop injectors or bigger, I don't bother. Just isn't worth it. I've passed up quite a few 32valve 4.6's.
