I am curious if any one can identify the injectors by the GM part #. Have a page that shows Bosch, Nippon Denso and some AC but not these numbers. First is 17120683 that was in LT! manifold from 94 Impala SS. Second is 17087325 also in a LT1 manifold but source unknown. Appreciate your help...Ray

 

Ray,

I'm not sure on the part number, but I'll check mine when I get a chance. Momma's '94 Impala has the OEM Lucas-CAV injectors (flowed by Cruizin' Performance of course) and they are reportedly rated at 3.64 cc/S, or about 22 lb/hr. @ 43.5 PSIG.

 

I was gonna say perhaps contact Rich at Cruzin directly and he should be able to easily identify them.

 

Ray,

Strike that. I went out and checked for a part number. They are NOT Lucas-CAV injectors, but are Rochester. I remember having talked to Rich at Cruizin' about them and I was afraid they were relabelled Lucas units, but they are not.
Unfortunately, as easy as it is to access the injectors on an LT1, I could not find a part number on them anywhere, despite the flashlight and inspection mirror. Just the "R-P" symbol near the electrical connector. When I removed the connectors, I didn't see a part number on those either.

Sorry if I mislead you earlier.

 

Ray,
The first number you listed (17120683) is from a L99 4.3L engine.
The second number (17087325) is from a LT1 5.7L engine.

Jeff, I'm going to have to send you a new pair of glasses. The part number on your injectors is 17095004.

Here are two sites to cross reference any injectors -

Cool.

 

Shadow,

I had a feeling you might have a small archive of data on some of those injectors. I must need new glasses - I even peeled off the markers I installed to identify the locations of the injectors, spun them around a bit, and saw nothing. "The Force" just ain't what it used to be...

 

Vadar, Don't feel bad......even with my bifocals, I have a hard time reading the numbers on some of the injectors. I guess it's just one of those "age" things.
