Interesting that all the engines in a line with Aluminum heads "appear" to be 1934 given the intakes and either the 40-6754 or 40-6750-B dip stick. The engines coming towards the camera appear to all have cast heads and a mid/late 35 or 36 style painted intake on them, presumably cast as well as the engine closest in the picture looks to have a painted intake?

The painted cast iron valve cover (intake manifold) is likely a truck engine.
