Hi just wanting to find out the correct oil capacity for my 1949 288ci engine in my deluxe club sedan with a H prefix on the engine number. My understanding is that the capacity is meant to be 5.2qt but the dipstick says full 7.2qt so I just want to clarify this....5.2qt brings the level up to halfway between low and full on the dipstick.
Cheers Rob.

Suffix H indicates the engine has optional hydraulic lifters and if the engine number has none of the suffix designations listed in the service note then the capacity is 6 quarts. For other specifications you can reference the 22nd series mechanical specifications in the service counselor. Typically an extra quart was added if the car had the optional accessory oil filter installed on the engine. To fill the actual filter and plumbing lines took less than a quart but the slight amount of additional oil caused no issues and dipstick was soon back to the full mark.

Verify you have the correct dipstick. This should help:
