Im listing this for the owner. He lives in Madrid, Ny. We took this out of his 1976 Buick Century with only 18k original miles on it. Excellent running condition. Removed today 52119.Buick 231 comes with 2-bbl carb, air cleaner, electronic dist. and motor mounts. Every bolt in the exhaust manifolds unbolted with little to no effort. Runs excellent.We pulled it to upgrade to a v8.
