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:

"search" the numbers on top of the injectors.
40 PPH
305/5.0 Liter L03, Camaro & Firebird (stock)
Green/White
GM 5235279 *RPD

I pulled this off another site.


55 PPH
350/5.7 Liter Pickup
Orange/Black
GM 5235206 *RPD


65 PPH
350/5.7 Liter Cop Car
Yellow/Brown
???
17112412

80 PPH
454/7.4 Liter Big Block Truck - Later Models
Blue/Black
GM 1708430 *RPD
17112560

90 PPH
454/7.4 Liter Big Block Truck
Dark Red/Dark Blue
GM 5235231 *RPD

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.

Thanks you guys have been very helpful.
