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.

This table helped me immensely in locating injectors for my TPI 327 project. It has nearly every make of fuel injector listed, with flow data, applications, and other important info. It includes both port and throttle body style injectors.
