My car is a 74 Nova, I think a inline 250?

My cars birthdate is 5/74.

The reason I’m asking, I was working on the car today running an oil pressure gauge.

And I noticed on the passenger side engine block was that paint stick stuff that they use at a junkyard. Said “73”. Hmmmmm

I cleaned everything up and....

CON2

F 214

848675

Then behind the distributor CE4 10709 Could be CF4, hard to see the one letter.

I can’t find this anywhere online. I checked novaresource and it’s showing three letter suffix codes? But not like mine. I don’t see anything like that.
