Right now I am rebuilding a 1969 327. I also have a Buick 350 with casting number 1231447, cant find any info on it anyware. Checked all buicks casting # and nothing. The head #'s are B 1233472. I was told that it came out of a 1970 skylark. The engine was free, just trying to get some info on it. Any help would be great.
Thanks
Tim
