Dipstick length?

About 8 or 9 quarts came out. It actually over flowed my drain pan. I used a long dipstick and made it match the stock one from my 73. yes I checked it with 4 quarts and again with 5.
I just got this car a week ago and it’s been about 12 years since I’ve had a early A.
Anyway on to the next project, passenger window is stuck up.
