Oil dipstick length

I'm in the final stages of getting my engine ready to drop in and I'm wondering if the dipstick is correct. I just thought of this now, I already put oil up to the level on the dipstick.

But im wondering if the dipstick would be different depending on the oil pan? The engine is a 360, with a moroso 8 quart oil pan does an 8 quart pan mean it needs 8 quarts of oil? I took the dipstick off of my old 318 with a stock car oil pan.

Would the dipstick be different? or are the "add and full" lines incorrect? The dipstick goes into the pan without hitting or interfering with the pan, and the dipstick tube goes in all the way. I think it will work, but just making sure.
