Dodge 250.6 CID Workshop Manual


Recommended Posts

Posted

Good morning everyone,

 

I am looking for a workshop manual to assist in rebuilding my father's 1959 Dodge Kingsway here in New Zealand. The car was produced in Canada and exported here to New Zealand. I have a workshop manual at home referring to a 1957 Desoto 250.6 CID engine, but finding anything Dodge, yet along Kingsway specific for the 250.6 seems to be challenging!

A PDF online would be ideal, as options for hard copies here in New Zealand are likely very limited.

I understand you have a manual?  If not or even if you do you might want to get the Chrysler industrial Engine manual from Vintage Power wagons.  Its really the best I have seen for the Chrysler based flat head sixes.  Don Bunns book Dodge Trucks has some build tips this is the book with the red and white pickup on the cover.  

 

I frequently copy posts put up for future reference i thought you might like to see this one.  You should have the long block 25 inch engine which was originally a Chrysler product where as the 23 inch engine was originally a Plymouth based engine as far as the original developers.  Dodge used both series of engines.  Desoto stuck with the long block as well as a lot of stuff in Canada.  US pickups and passenger cars mostly used the 23 inch Plymouth based engine but big trucks used the 25 inch engine as well as larger passenger cars and trucks over 1.5 tons.  The 25 inch block should be what you have.  It came in both divorced bypass filter systems and full flow systems that were integrated in the block.  By 57 you could have had the full flow system.  The file below was originaly posted by a vert talented guy who had a 3 ton big truck fully restored the engine with the dual exhaust went into that but those are special engines only seen really in this kind of application.  You will notice the woodie he restored as well.  Both really nice.  Hope this article helps.  Big block engine types.doc

Thanks for your response, Robert.

Yes, the engine I have is the 25-inch block. Shipping to New Zealand is very expensive, hence why I would prefer an online version if possible. From what I've found so far it has the bypass filter system (seemingly a topic of hot contention when it comes to converting to a full flow system, which I am in the process of considering doing)

I'll have a read through your article attached - thank you for that.

The book I have does refer to 1957 Desoto's with the 250.6 engine, so I think I should be able to use most of that information for the 250.6 engine in my 59 Dodge, some things may be different, but hopefully the guy helping me re assemble the engine should find everything he needs in the one I've got. If anyone has an online version more suitable I'd love to have access to it!
