955 oil pan capacity, 5 quarts?

5.2 mag in my '64 Barracuda, with a 955 oil pan. I'm trying to get a dipstick/tube configured for it, pretty much by measuring the combinations on my other cars. Stick length should be close (enough), but with 5 qts poured in, and nothing in the filter, it's showing at the low mark on the stick. I just want to make sure that this pan is designed to hold 5 quarts, before I re-mark the stick, or lop a bit off the tube.
Thanks, Karlin.
