I have a 2000 blazer that I don't know what it has for injectors.

Sorry for not replying sooner, I didnt know your message was here. I was searching for another issue on the Blazer and saw your post.

The job was pretty easy. I did the same thing on my 97 Tahoe which is the same thing with two more cylinders. I went with the updated style and did the same on the Tahoe. I did see a performance increase on the Tahoe, but couldn't really tell on the Blazer. The hardest part was taking the fuel lines off at the back of the engine. Other than that, just watch what goes where. I used some tie straps to keep the wire harness out of the way. There are other components attached to the manifold so watch for those.

Feel free to PM me if you need more info.
