‘78 440 cam button? Oil slinger?

Oil slinger........ Mine was missing also at tear down but I did get one and installed it. From what I understand it helps oil the timing set.
Prob will not find a cam button if the engine had a flat tappet cam.

Stock 440's did not have cam buttons. Three bolt timing setups can use the button. I use one. The slinger is a good thing, but may not be required.

slinger does 2 things. puts oil onto chain and protects the crank seal.

Roller cams need a cam button more than the others.....

Yep yep called oil slinger because thats what it do slings oil
If I recall, Chrysler deleted the slinger when the double lip front seal came into use.

Oil slinger, yes. I would put one on. Cam button, no. The cam drives the distributor gear/oil pump and thus thrusts the cam gear
against the block face.
against the block face.

oil pump theory works till you get on and off the gas
cam can slam back and forth
taper on the cam and crowned lifters also controls

As long as the engine is running, the pump is pumping and the distributator is distributin! Ha!
I never saw any marks on the timing cover, and me thinks the fuel pump accentric would let the
push rod fall out of position and then Oh My Lordy! Don't wanna go there.

My opinion, the cam in a BB does thrust forward. May not be much.

Flat tappet cams, both hydraulic and solid, have a taper ground into cam lobes amd lifters that push the cam back into the engine, both to locate cam properly, and to rotate lifters for longevity. What d3te4mines cam location therefore is the face of the cam gear that rubs on the front of the block.
Roller cams,both hydraulic and solid, due to having a wheel on the lifter, cannot use a taper, therefore they must use a cam button, and usually some reinforcement of timing cover. Almost all rollers use a three bolt cam to be able to use a button. (I try to never use "always")
I would use the oil slinger, as previously mentioned, it helps oil the chain(and timing chain face to block) and keeps the front seal from being overloaded with oil.
