G'day all. On the 460 block in front of No 1 cylinder I have a number including a couple of letters 3C0BH (or something similar can't remember) which I am lead to believe is the engine number. Below this is an up-side down A and to the left is an up-side down 93 (year of manufacture?). Can any clarify these marks?

LWhittington,

The year of manufacture is not quite as important as the engineering revisions, or "casting numbers."

The cylinder head casting numbers are located on the outside of the head, along the valve cover mounting rail and between the 3rd and 4th exhaust ports. The are visible simply by raising the hood and looking at the engine. You should be able to find a cast-in alphanumeric number, possibly one of the following:

• C8VE-E
• C9VE-A
• D0VE-C
• D2VE-AA
• D3VE-A2A

Or, it may appear similar to one of the above numbers but a little different.

The block casting number is located on the ouside of the engine, at the rear of the cylinder bank, behind the starter motor and reads vertically. There, you should be able to find a cast-in alphanumeric number, possibly one of the following:

• C8VE-B
• C9VE-B
• D0VE-A
• D1VE-A2B
• D9TE-AB

Or, it may appear similar to one of the above numbers but a little different.
