All this talk on aluminum pistons, I was just wondering -- what is the first Chevrolet built production engine to use Aluminum pistons?

Here is a hint:
The piston manufacture of the first Chevrolet built 4 cylinder production engine that used aluminum pistons, was The Aluminum Casting Company, Cleveland, Ohio. In one of its adverts, in which it listed Chevrolet Motor Company as having adopted aluminum pistons as standard equipment, explains "What are the pistons made of?
Are they of cast-iron, overweight, slow-gaited cast-iron, with its hammer and pound? Or are they made of aluminum, strong as cast-iron yet weighing but one-third as much, making the pistons nimble and quick and soft of tread?
Until a few years ago practically all automobiles engine pistons were cast-iron. Today cast-iron pistons are fast passing into memory.
The explaination is simple: From 40 to 50 times a second, depending on crankshat speed, the piston makes a round trip in its cylinder -- 100 starts, 100 stops, almost in a clock-tick. At this high speed, any decrease in piston weigh means increase flexibility and lessened vibrations."
When I asked this question this morning, I admit I did know the 1918 Chevrolet Model D uses 8 Aluminumm Casting Co. pistons in its engine -- the V8 engines built at the Chevrolet Engine plant in Bay City, Michigan. However, a 'Twin 4' doesn't technically qualify as a Chev 4 to which this 'First' aluminum question applies. Now that I have done my research tonight, I can say it happened before 1928.
