Question about Chevrolet Malibu
Go to a parts store and ask for the degree but the motor condition timing chain and distributor all are factors here and rustfarmer is dead on the money here because worn or weak components will throw the timing out of range for the right setting trial & error here get it to run without overheating and the most power//but new stuff if replaced properly and dialed in cam/crankshaft correctly will be that degree from auto parts

There is no good answer as factory timing assumes brand new engine and all stock exhaust, ignition etc parts, plus kind of hard to buy 1964 gas. I would start at 4% Before TDC. Then drive the car at WOT to see how it runs. Advance timing a little at a time to see when you begin to get pre-ignition, then back off just a bit. Always check the vacuum advance and mechanical advance units for proper operation first. I have a 63 Bel Air with the 230 engine and found some prior owner had replaced the advance springs with very weak ones in an apparent attempt to gain power. Result was the dizzy was advanced so much at low rpm no real advance happened as the rpms increased so it ran very poorly. A bad vacuum unit also creates havoc with timing.

I do believe one is a VIN code and the other is a manufacturer date code, it's not known for sure ? as threw the 60's chevy changed codes and matching numbers, with enough Google searching you could find out for sure ?

Although it is not always possible to tell if the engine you have is the original, the best bet would be to either buy a book of chevy casting numbers, or join a chevelle forum and ask there. I will say that in 64 the stock intake manifold had a oil fill tube at the front which I don't see in your photo. You might look at the driver's rear of the engine block for casting numbers and post here to see if someone more knowledgable than I can help.
