I have 2 cast iron manifolds one is casting# 3886922 Date Code E285 (May 28, 1965) that was for a SBC 283/327, the second one is casting# 3844457 Date Code K235 (Nov. 23, 1965) that was from a 327 CI 250HP Vette. Also I will include a 4BBL air cleaner from 1964 (hard to come by in California). The price is low to move them to a new home as the air cleaner would fetch almost as much as I am asking for all. The 65 manifold needs a good cleaning as it sat in my yard for a few (LOL) years. Great find if you are building an early 60's SBC and want original parts.
