Block= ECZ 6015C=292/312
Exhaust manifolds R=B9AE, L=EDB (58-59 292 manifolds)
Water outlet=ECE-8/3
Intake=ECZ-9425-B

So my guess is this, the engine is a genuine low mileage 312 (well at least at this point in time) that went to the fairlane I got it out of. But at some point the heads and manifolds got replaced along with the valley pan. The only reason I say this about the pan is that it was designed with a PCV valve in it from the factory. It has a stamped indentation where the valve sits so I don't think it is a later mod.

This engine was pulled from a 57 FORD sitting in a salvage yard?

My thoughts ( ) is that somewhere in the engines service history, the heads were replaced as possibly the assembly heads needed servicing, and the later heads were probably cheaper from a salvage yard than having the originals machined. And they lowered CR enabling using regular gasoline.

The right EXH MAN goes with the later heads (DATE CODES are necessary to nail down what is correct and what is not).

As for the valley pan, most likely a PCV upgrade from a later engine to rid the road draft system.

The intake is correct for 1957. Is there any ID on the carb?

The engine was upgraded through its service history as FYB TECH progressed.
