The same timing chain cover was used for both '64 and '65 and had just a simple pointer. These were cast with number '''9773371'''. The timing cover used on '66 and '67 employed a small timing scale marked -4-0-+6 and is otherwise identified as casting #'''9783130'''. The '68, '69 and '70 timing covers look very similar with timing marks of 0-6-12 degrees BTDC and accommodated the large diameter damper. The '68 timing cover casting number is '''9790347''' and uses the 8-bolt water pump. The '69-'70 timing cover casting number is '''9796346''' and uses the improved 11-bolt pump. For '71-up the timing cover timing tab is marked from 4 degrees ATDC to 12 degrees BTDC and is graduated all the way to 16 degrees BTDC. As compression ratios were lowered to 8:1 and less there became a need for increased initial advance. Casting number for this cover is '''482883'''. If you need to order a water pump the Federal Mogul part numbers are: '64-'68 is FP1388N, early '69 is FP1409N and late '69-on is FP1423. | The same timing chain cover was used for both '64 and '65 and had just a simple pointer.
