The Stovebolt Site Forums The Shop Area Engine Shop What engine do I have in my 1934 Woodie?

Tim:

Thanks! The engine is kind of messy. It was broken over 20 years ago and then left sitting till I got it. Only thing that I could see are the cast numbers on the right side of the engine, which are:
GM
J18-4
831231-6

From my paperwork, engine number is/was: K4706976 (I need to verify it physically, if I find out where to look for that number). According to this number and using the info posted by 53John3100, it is a Master, as " "K" for "Master Series C[K]OMMERCIAL"*; ".

So, question now is, what engines did the Master series, commercial, used?: a 194 cu.in. or a 207 cu.in. engine?

Thanks,
Victor
It has a serial number plate: 3DB11 58720
