I have a good set of Hilborn one piece injection. As far as I can tell look to be 2-1/8" and come with stacks Aluminum Air box and used K & N Filter as well as 3-1/2" Nozzles. Linkage and Barrel Valve. Would make a good set for vintage guys however I have been running these for the last 10 years and bought a larger set for next season and am needing $ the get stuff together for next year. Asking $650 for all of it. Going to clean it up and post picture soon, as I just removed from the engine. Email me at
