Good Product, These fit holley high ram, i showed a picture of my injectors im running. Keep in mind injector length can change depending on what injectors you have. These look work and lock in great with the bolt hole lining up on the top.

I swapped my truck manifold for a LS1 intake to make it fit in my jeep better and these make my truck fuel injectors work without any problems

These work perfect! I thought they were anodized black by the picture but they are just finished aluminum. I recommend putting the cups on the injector first. They are difficult to install at first on the injector. but if you work the o-ring around and add a little lube they pop right in.

I swapped an LS1 intake manifold and fuel rail onto my LM7 5.3L. It's fine to use LS1 injectors on a 5.3, but you would need a tuner to set the car up correctly. I wanted to keep using my existing tune, so this was perfect. I did have to cut and remove a black plastic nip from the end of the injector for it to fit correctly into the manifold. I made a small cut with an angle grinder, then finished removing it by just taking some pliers and lightly twisting until it cracked in the previous cut and was able to slide off.

I used these to install ls3 style injectors on a gen 3 truck intake. The overall length was taller as expected so i did need to add spacers to the rail mounts. Everything is working good with no leaks.

Haven't gotten to try it yet. But it definitely seemed to have worked for what I'm doing. My engine is all black and I'm giving it a 3 star because it hasn't come in black like the picture shows.I can update the review once the engine is running but I have no doubt it'll do what it's intended.Also, I found it abit prices for what it is... but I guess if you're stuck and need it.. you have to pay the price.
