Really cool early find!! Are you doing a full restoration or just a preservation?

At this point just a preservation. It is really complete so if we can get it running it should be drivable for parades, shows, etc. It is really beat up. A full restoration would be a lot of work!

We're working on that! Pan needs to come off as there are some rust holes in the bottom due to condensation(I hope). Oil looks good it it and not overfull. Fingers crossed.

Great find! A rare beast definitely. Congrats on the purchase!

Speaking the engine I would pay attention to what firetruck guys have in their old Macks.

Ive wondered if that was not to keep fuel from overflowing and running into the engine?  Something along those lines?

Yea there is old iron literally laying around everywhere over here. Everybody’s garage or old barn has stuff sitting in it. If you take secondary and rural roads through just about anywhere in the States you will see stuff sitting everywhere. Kind of sad in some ways and kind of good in other ways I guess.

Not everybody but there is quite a bit. The sad part is when it is left to rot into the ground

I had occation to measure a bc engine looking for a cylinder head for a CF engine in a BM truck The head bolt pattern front to back measured the same but the BC engine was 1 inch nerrower measured across the block  than the CF engine. The CF is a 414 CU" engine so my quess would be the BC would be aprox 350 CU".You are very fortunate to have a pristeen EX manifold.

Up draft carbs were most likely used so as to have gravity fuel flow to the carb. All gas powered tractors had their tank above the engine and of cource the Model A ford with the tank in the dash.
