I have a Chevrolet 6 cylinder engine to ID. Block is stamped F0425J or FD425J Cylinder head is cast 3836848. Anyone know let me know. Thanks, Bob,
http://www.inliners.org/becks/BCN2.html You're looking at the wrong block numbers I think... but the head casting comes up as 1956 235 http://clubs.hemmings.com/clubsites/chevytalk/GMhistory/1916-57cast.html
