I have up for sale a brand new, NEVER installed, Holley Sniper 550-510 fuel injection conversion kit. This unit is brand new and has never been installed. I only opened the box to make sure everything was included and to take pictures. The part number on this unit is 550-510 which is the polished or shiny throttle body assembly. It comes with all the necessary parts such as the 02 sensor, temperature sensor, wire harness, handheld touchscreen, etc. You can look this part number up on Holley’s website and they will provide all the specifications and information on this unit. I bought this kit last year with the mindset that I was going to convert my 67 Camaro over to fuel injection this upcoming winter. But just recently I was able to score a low mileage LS3 engine and I’ve decided to swap my car over to an LS. So I no longer need the Sniper. I realize that my unit is from last year and while new and never installed, I feel better offering it for a fair price. Here’s the info right from Holley’s website.
