I've been doing a little late winter cleaning and came across a couple of sets of injectors. Of course they aren't tagged so I'm not sure what they came out of. One set is short and I think it's from an 8.1 truck. The other is a standard size. They look to be from an LS1. I think I remember seeing a site that had injector pictures to compare. Has anyone seen this or have a good way to identify these? I tried matching the numbers with GM but no luck.

Thanks!

 

Racetronix's site has pictures and part numbers for a ton of delphi, siemen's and other injectors -- may wanna start there. Also, you can try searching for the part number stamped on the top of the barrell (usually opposite the plug)
