I just did my first oil change on my 68 442. The dip stick was reading low before I started. I drained out 9 quarts and the filter.
I put on 7 quarts and get no reading on the dip stick.
could this actually take 9 or 10 quarts? I don’t know if it was overfilled when I got it and maybe it’s the wrong dip stick.
Could the

pan be a racing (more capacity) pan? This car came from 1/4 mile racer Bob Voss with a 4.66 gear in it, so aftermarket racing parts are likely.
here’s a picture of the pan. Hoping for advice before I over fill. Thanks —Billy

 

that is definitely not a stock pan. Nine quarts is probably normal for that pan.

 

Seems like if you drained out 9 qts and the filter, you would have to put back in 9 qts and the filter. 91/2 quarts? That sure is a big pan! Badass looking headers too!

 

Conventional thinking is that one benefit of a big pan is that you an lower the oil level from the crank for less windage. Eight quarts should be more than sufficient.

 

Thanks. Just afraid I’ll overfill it. —Billy

 

Here is a better picture of this custom oil pan. Problem is that the installer left the 21 1/2 inch stick dipstick so I’m not getting a reading even on 9 quarts. Eventually I’ll change to a stock pan. It’s bugging me not knowing what level I’m at. —Billy

 

Maybe the next time you change the oil you could use a scope to see where is the pickup? Its probably down near the bottom but don't count on it.

 

You should be able to do some very rough calculations based on measuring the bottom section of the pan to calculate the capacity.
A web site like this might help out: https://www.sensorsone.com/length-wi...me-calculator/

Knowing the pickup location would be excellent information. If it's positioned correctly at the very bottom of the pan then as long as you don't over fill it 9 quarts should be good. You might have to build your own dipstick though.

I notice the ram air scoop in the last photo - nice!
