'96 Z71 ,5.7l fuel injector question

I have a 96 Silverado Z71 5.7 vortec ,and I'm wondering if the Delphi spider injection is any good.
Any recommendations ?

Delphi is good I’ve used the upgraded MPFI injector assembly with great results in the past. I believe Delphi is/was the oem supplier to GM. I know that is the case for the GMT 400 fuel pumps as well.

Look like never used.
