FW340sP340469 - this is the engine serial number. (Not to be confused with the VIN number)
It decodes like this;
F - Series (model year) 1970
W - Windsor, Ontario engine assembly plant
340 - 340 cid
s - Special, T/A block in this case.
P - Premium fuel only
340469 - two numbers missing, can you double check or add a photo?
The casting date is the date the block was cast.
The other number is the casting number for the T/A block.
On the passenger side of the block, down low is a flat pad. What are the numbers on it?
