I have an 87 z and just put a set in w/an AFPR of course and they work fine but they are a bit noisy but don't worry,thats normal.I have my fuel pressure set at about 44PSI at idle and vacum hooked up and mine is a 350 so if yours is to do it makes a little difference.

The 92-93 LT1 injectors are 22lbs, the 94-97 LT1 injectors are 24lbs. They work fine in TPI engines, I am using a set of 24lbs in mine now.
