Hello i found this numbers on 1970 340 six pack on original engine Stamped on Block LH side front bellow the head FW340sP340469 also
on Block RH side Casting 3577130.T.A.340. and 11 26 69 can you help me to understand and decode this numbers Thanks Abe.

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?
