No problem at all sharing Gene. That is how information is gained and spread. I think you are right in that I mis-read the casting number on the 46 truck block. It is most likely a C59 .
Still wondering if anybody else has ever seen a block stamped with "49" at the left front top between head and intake manifold like my 39 Deluxe has. Rebuilder's tag is dated 1952 so I am wondering if they rebuilt a 49 block and this is what my car has.
RalphG; 1949 block is late flathead 8ba (US 48-53) 48-54 Canada.
No integral bell housing --bolt in adapter tween engine
and trans. No known records kept on machinist's stamps on
48 and earlier with integral bell hsg.
Rebuild tag is on bell, so 48 or earlier , not late flathead.
How's the farm work going?
More later
