426 Max Wedge Oil Pan Specs (’63-’64): Capacity and Pickup

Let’s examine the oil pans for the 1963 and 1964 426 Maximum Performance (nicknamed Max Wedge) engines.

The 426 Max Wedge engines have a 5-quart oil capacity and a front and rear baffle. The two baffles helps with oil control during acceleration. The oil pan uses a swinging pickup for oil transfer to the rear of the pan during acceleration and to the front during deceleration.

The 5-quart capacity is for the pan only. Oil changes when changing the filter requires another quart of oil for a total of six quarts.

The same oil pan is used for both 426 Max Wedge engines and years, 1963 and 1964. This includes the following:

  • Plymouth Super Stock 426
  • Plymouth Super Stock 426-ll
  • Plymouth Super Stock 426-lll
  • Dodge Ramcharger 426
  • Dodge Ramcharger 426-A
  • Dodge Ramcharger 426-lll

Let’s take a closer look at the pan, baffles and pickup tube.

In addition to the increased capacity of a regular wedge engine, a main feature of the pan is the two baffles. One baffle is located in the front and the other baffle in the rear.

Both baffles help to control the sloshing of the oil in the pan. This helps keeping as much oil as possible at the bottom so it can be picked up by the suction pipe (pickup).

The 426 Max Wedge oil pan capacity was verified with the Plymouth and Dodge Max Wedge owner’s manuals, booklets and Vans Auto who sells a reproduction oil pan.

426 Max Wedge Oil Pickup

The 426 Max Wedge has a specially designed oil pickup. The bottom part of the pickup, where the strainer is located, is made to swivel.

During acceleration it swivels towards the rear of the pain with the oil. During deceleration it swivels to the front of the pan with the oil.

The size of the pickup was enlarged in 1963 for the 426 to 1/2″ diameter. The previous 413 Max Wedge had a 3/8″ diameter pickup.

About 38 years ago I assembled my first Mopar engine. It’s at that time my hands on experience with Mopar engines, including the Max Wedge, started. Although my research of the engines started years earlier.
