Hi. I've seen the chart that shows the color combinations for different injectors, but I'm very dumb and don't know where to look for these colors. I have a few sets of injectors that I pulled off of v8s in the wrecking yard (2 from vans one from a truck) and the emissions labels were all gone so I don't know if they were 5.7 or 5.0 engines. How do I tell? Here's one:

65lb is 17084327
80lb is 17084304

There are also many other GM casting numbers that are on the injectors. Example is 5235306 is a 90lb injector which is the same as the 5235231.
