Rick Marsh Posted July 28, 2019 Share Posted July 28, 2019 I have a broken beyond repair exhaust manifold on my 1931 Chrysler CM6. A previous owner "upgraded" with PN 603033 which is either an early 1930s Chrysler or DeSoto. I'm in need of a PN 603033 replacement or an intake / exhaust pair that fits the stud pattern. It is two parallel rows of mounting studs with 23 1/4" from front to rear stud. Thanks in advance for any help. Rick Marsh Link to comment Share on other sites More sharing options...

Clane422 Posted July 28, 2019 Share Posted July 28, 2019 Does it look like this i have 4 more not sure of the years yet though Link to comment Share on other sites More sharing options...
keiser31 Posted July 29, 2019 Share Posted July 29, 2019 I have a set of manifolds that I believe will fit. They are from a 1931 Dodge Brothers DH6. The only difference I see is that the Chrysler upper portion is round and mine is rectangular. The 23 1/4" dimension is the same. Link to comment Share on other sites More sharing options...

Rick Marsh Posted July 29, 2019 Author Share Posted July 29, 2019 The intake and exhaust ports appear to be the same as in the photograph offered by Keiser31. I agree that my 1031 Chrysler CM6 should look like the image you shared of the engine compartment. That is the original setup with an updraft carb. I no longer have that. My car was converted by a previous owner to a downdraft carb setup. I assume the 1931 Dodge setup you have requires an updraft carb. Do you have the carb that goes with the Dodge intake and exhaust? Do you also have the air cleaner? Thanks, Rick Marsh Link to comment Share on other sites More sharing options...
keiser31 Posted July 29, 2019 Share Posted July 29, 2019 (edited) I have no carburetor or air cleaner for that one. A Carter BB-1 would probably be the one you want. That is what is on the manifold in the last photo. Edited July 29, 2019 by keiser31 (see edit history) Link to comment Share on other sites More sharing options...
Rick Marsh Posted July 31, 2019 Author Share Posted July 31, 2019 I guess I'll look for a Carter BB-1 and get back to you Thanks, Rick Marsh 1 Link to comment Share on other sites More sharing options...

viv w Posted August 1, 2019 Share Posted August 1, 2019 Is the car right hand or left hand drive? as the 2 types are probably different. Link to comment Share on other sites More sharing options...

Rick Marsh Posted September 10, 2019 Author Share Posted September 10, 2019 Good morning, I would like to thank all who replied and offered assistance. I now have a 1931 Chrysler CM6 that has been returned to the correct updraft configuration. It has never run better. I look forward to driving it on the Glidden Tour later this month. Thanks again Link to comment Share on other sites More sharing options...
