| Tim, are you sure it is a 390 block?Check the bore size,I have seen 428 blocks with the A cast into the back,but the date code sounds a little late for a 428.CJ blocks had a C cast in the same spot but I don't know if that applied to all of them.I've had 3 and they all had it.I've had 4 or 5 regular 428 blocks and they all had the A.If you don't have calipers a standard 390 will be about 4 1/16 while a 428 will be about 4 1/8 bore size.Also if you look into the water jackets you may be able too see 428 cast into the bottom. |
