DA 6 engine differences

[stakeside]

Per Dodge Brothers “Confidential Bulletin No. F-3” dated Feb. 15 1930 a new improved DA6 truck engine will be introduced. Memo stated this engine is best suited for the 3/4-ton, 1-ton, and 1 1/2-ton Trucks. It is designated as the new “Truck Motor” produced on a new separate production line.

 

1. Any idea what were the improvements? I am not aware of any differences in displacement and horsepower of the DA-6. Could be possible that there is improvement in size of the main bearings.
2. Any body have a DA-6 truck engine with a fuel pump. If so could you give a “H-xxx” motor number? I found there is a fuel pump noted in the “master Parts” for the DA-124 and U-124.

 

It might be that the announcement to the dealers was a marketing smoke screen.

I know of a member who has a DA6 in a DA124 Express Body

Eng# H1473xx but I'm pretty sure the change came a few thousand engines prior (from memory). 

Will try and locate that info. 

 

 

This member does not have the fuel pump in a DA124 Panel same as the donor engine in my truck now.

His Eng# is H1448xx

 

My original eng# was H1467xx and I believe mine should have had the fuel pump (from memory, could be wrong). Again, can't recall where that info is or how I came to that conclusion but will try and retrieve it if needed. 

I believe the answer is somewhere in the MPB if I recall. 
I do not have the original engine for my truck, only my build card showing the engine #.

 

Let me know.

Looking at my “Master Parts” I noticed different crankshaft listing.  The Stockton or S frame numbers after S112xxx has a different crankshaft listing. Both of my frame numbers are after S112xxx.

What is the range of DA6 engine numbers?

Also, are there part numbers and casting dates on the engine block? If so where are they located?

I believe the highest # would have been around H1508xx base on a few factors. The only way to prove that is to contact the Chrysler museum. I did try that a few years ago when I asked for the last DA6 engine produced and already asked what the last truck model was made in the E series frame #s but they will not release that data unless I own one of those trucks. 

 

As for the casting #'s, I believe Eric Bannerman has collected much data on that and might be able to help.
