			I recently read on CRG that 618 cast blocks for 1969 Camaro were cast at the Flint plant. My car has a 618 cast with a Tonawanda stamp on the front pad. Does anyone know if 618 blocks were possibly cast at Tonawanda?

			Is the pad stamp on your block a Camaro application code?

			Yes, HA(4sp). Date is several weeks prior to production date provided by NCRS.

			Do you have a picture of the stamp?  
		
		
		
		
		
		
			Does it have the lifter galley plug above the timing cover? The square shaped plug to the right of the stamp pad....

			If it doesn't have the plug it was machined at Tonawanda and many HA's were built there, I've got 2 in my own collection.
