TBI Injector part numbers
I researched these and this is what I got.
GM Part number 17113080 7.4L TBI injector (1994,1995)
GM Part number 17112560 7.4L TBI injector (1991,1992,1993)
GM Part number 17111784 7.4L TBI injector (1988,1989,1990)
GM Part number 17112493 5.7L TBI injector All years
GM Part number 17112400 5.0L TBI injector All years
GM Part number 17112521 4.3L TBI injector 88+
I thought the newer 5.7L trucks used different injectors but I could not find any other part number than the 17112493. I don't know what the differences are in the 3 types of 454 injectors. They are all about $97ea at www.gmpartsdirect.com
They didn't have any part number listing for the cop car injectors which would be nice to be able to get a new GM replacement.
