The stock motor was a 229 V6.
The number you gave me off the front was a re manufactures tag for when they rebuilt it. It is a small block between a 267 and a 400 cubic inch engine. Once the heads are removed and the cylinder bore measured, then you can get the actual size. It most likely was bored out larger than original.
Sorry I cannot give you exact information but with this you have to wait until it is torn down to get the actual size.
