The Mopar is cast on the siamese bore block but not on the water mega block.
I wonder if the Chrysler star on the hemi block I posted and it missing on Doug's block where mopar is cast has anything to due to what year the blocks are or maybe it's a hemi wedge thing or someone just removed it from Doug's block????
Mine is siamesed and cross bolted. I am curious as to why the chart list the standard bore at 4.19"?

Mopar offered that block in a 4.19 and a 4.50 bore but most of the 4.50 bores were a lousy bore so most had
to be over bored.. thats why most guys got the 4.19... thats what I did also
EDIT
also the numbers you are looking at are just casting numbers..pay no attention to them.. if you look they arent
listed in the parts list above
