That looks like a GM injector. As for if it's the stock injector for that car, I can't say.

Looks like the GM multecs they are chevy injectors and they came on camaros but i think they are 21lb injectors, 5.0L should be 19lb.

From the picture I can say they look EXACTLY like the stock 22# GM Multecs I used to have in my L98.

What those are, their rating, how old they are.......I can't say.

Re: are these stock injectors?..pic inside

To be sure you could check the numbers, but they do appear to look the same as my 22# GM injectors. Here is a pic of mine- one is a newer change up but still 22#.

I'm giving the numbers here for you, too. Hope this helps. Jim
