PJ,
Depends on the pan too. Both of my 385 series blocks have the aftermarket Ford Racing pans that have 6-quart capacity; alas, one has a dipstick going to the pan. Fortunately the Cobra has the front cover type.
I measured the one in the Cobra and what I found is going onto my web site here:
First Coast Cobra Club • View topic - Dipstick measurements
Hope it helps.
Tom
