Bought this setup a bunch of years ago from a multi carb rebuilder guy in Carlisle. I lost his card, but he is still there Spring and fall. Always asks if I used it yet??? I have a 57 392 that I was going to build a car around someday with this intake. Casting # 1634285 and date 10/58 Correct rebuilt carbs and linkage with fuel line. Includes 2 new 7" air filters
