This listing is for a small block Chevrolet intake manifold, casting number 3872783. It is dated "L 7 5". The heat shield on the bottom is dented. Other than that, the intake appears to me to be in good condition. While this will fit many different small blocks, I believe this was originally used on 1966 and 1967 Chevy 327 with a factory installed performance carburetor(Holley?).
Please look at the pictures carefully and feel free to ask any questions.
Thanks
