[oletrucks] Engine ID help

["Antonio R. Tijerino" <antonio@innercite.com>]

I have noticed that we can get help IDing oletrucks engines from members
of the list. I guess now it is my turn. If someone can please help me ID
this engine here are the specs:

Engraving next to distributor: 0939635F54Z
Casting under Fuel pump: 3835911
Head casting: 3836848

Thanks in advanced.

Antonio,
'53 3100
