440 Oil/Capacity

I want to do an oil change in my 440, since it has not ran in about 4 years

What oil weight should I use and how many quarts (should I take a pic of the oil pan to verify?)

The motor I believe is a 1968

I looked at the passenger side of the block and found these numbers:

25364305
3 . 31 . 67

On the ID pad:
D 440 (cross symbol) B
7 31
Anyone else notice the OP is changing oil on an engine that has ‘not ran in about 4 years’.
Ok, is this action being done as part of a plan to start the motor?
Or is the oil being changed because it’s been in the engine for about 4 years and the engine will continue to sit?
