I am selling a set of 8 LT4 nominal flow injectors. They were used in my l83 GMC truck for about 500 miles. The injectors have two different part numbers. I have six injectors that are 12681512. The other two injectors are 12701125.

I had difficulty tuning with them because I believe running two different part number injectors was causing my issue. Im not sure what exactly is different about the two part numbers. I took them out and replaced them with a different set.

I am willing to sell the set of 6 Injectors or the set of 2 injectors apart from each other. All injectors will come with brand new seals,boots and clips. The seals need to be replaced since you need to replace them whenever you pull them out of the engine. I bought these injectors new from ADM Performance about a month ago. They worked perfectly fine just couldn't dial in the fueling in the tune.

I'm asking 100$ for the set of 2 injectors and 300$ for the set of 6 injectors. Prices are shipped and negotiable. Thanks for looking. Please pm with any questions.
