Is a 75 360 LA supposed to have a oil slinger?

if you're interested my '72 340, in a car that I bought when it had 58k miles.
I took it down for a cam swap and found no oiling "tab".
It had the 3 regular bolts and the one drilled bolt.
It also had the crank slinger.
Every other 360 or 318 2v that I've worked on had the oiling tab and the 3 regular bolts.
None had the crank slinger.
Another way 340s were special!
