I want to verify the date on the engine block of the 327 that came out of my 1966 Suburban. Casting # on rear of block is 3858174. The other casting numbers I find are on the back of the block which would be under the flywheel. H5 174. Is this the date or do I need to look somewhere else for the date? Thanks, Jim
