Zippo cig lghter size tin vent can below on rt front of oil pan.
Need more info re numbers on heads, etc. For a start to id. Main bearings
next if 1936.
Trans mount is 35-36. The pan is not 32-34 so probably also 35-36. It looks like a truck engine from the fan. I think the trans top changed in 36 so I call it a 35.
