I am trying to troubleshoot a fuel issue with my 93 LT1, and am trying to determine which injectors I have. I took a look at my injectors to see if there was any text on them to identify if they are stock or not, but could not see any markings. Is there an easy way to tell what injectors I have? Mine look like the standard injectors shown on Rockauto with the metal base and plastic upper body:

 

Anyone?
