Z-Rod oil, 20w50Amsoil hotrod oil or what they recommend, just call the tech line. Best oil made bar none.
After reading through here and based upon local availability, decided to go with Valvoline VR-1 and a WIX filter. Local NAPA store was able to hook me up.

Off topic, but why is your alternator bracket upside down ?

And while I'm at it, you might want to lose the glass fuel filter, and air cleaner.Both have been known to catch on fire.
Back to the regularly scheduled programming.
Another " constructive criticism" if l may.
You are almost out of adjustment on alternator belt. You do not have to do this today, but may want to consider getting a belt that is about 1/12" - 2" shorter.
Start adjustment close to motor as possible.
New belts DO stretch. A belt will get longer. Never shorter. ( Unless it brakes. Duh)
It will not " flex" / vibrate as much. Also a little less likely to "squeal".
Wipe down pulley grooves with brake clean or lacquer thinner to remove residue.
I usually even take a piece of 180 grit sandpaper to slightly " roughen up" the grooves before installing new belt.
Been doing this method for years on dirt and asphalt race cars. Never had a belt issue since started doing it.
No reason why 5 minutes of extra work that it won't work on a street car as well.
And yes, l do it in my street cars.
You are learning. That is a good thing. Keep it up.
