Expert 5K+ Posts: 9911 Location: Lower Mainland BC | . This table will be used early in the post that I want to do about the 53-57 Dodge Double-Rocker ("Hemi") engines. As before, a lot (almost all in this case) of the info comes from Willem Weertman's book ("Chrysler Engines - 1922 - 1998") In compiling the data from this book into this table, I was surprised that the first Desoto and the first Dodge double-rocker engines had the same bore spacing and the same block length (but different deck heights) so different blocks (but not by much). Interesting that the calculated hp/cu in is the highest in the Dodge 241. Good for the Dodge boys!! I am hoping that somebody can help me fill in the missing carb numbers for the 51 Chrysler and 52 Desoto 2 bbls. (I still don't have that Leo Lingquist hemi data book).

Expert 5K+ Posts: 9911 Location: Lower Mainland BC | . Thanks very much Chuck. Again, I hope that that was a cut and paste job, because otherwise, that was a lot of typing. Thanks. I've actually been able to find a Carter water-cooled (heated?) WCD 931 2bbl on eBay. Interesting but scary. https://www.ebay.com/itm/CARTER-WCD-CARBURETOR-1952-CHRYSLER-331-8-C... Thanks again.

Expert 5K+ Posts: 9681 Location: So. Cal | Here are the '52 DeSoto 276 hemi carbs: 1952 8 276 S17 fluid drive Carter BBD 901 1952 8 276 S17 S/T Carter BBD 905 1952 8 276 S17 S/T with O/D Carter BBD 906 1952 8 276 S17 fluid drive Carter BBD 908 1952 8 276 S17 S/T Carter BBD 909 1952 8 276 S17 S/T with O/D Carter BBD 910 1952 8 276 S17 Carter WCD 884 They vary depending on transmission used. That 324 in the '51 Chrysler carb data has got to be a typo for 331. I've never heard of a 324. | ||

Expert 5K+ Posts: 9911 Location: Lower Mainland BC | . I can see now where folks are getting some of their carb numbers from (thanks): https://www.thecarburetorshop.com/Passengerkits.htm On that basis, and the numbers that I have been given, I have revised the table to appear like this now: Edited by 56D500boy 2021-03-27 8:53 PM (Table1Gen1MoparDoubleRockerEngineSpecs_Rev1.jpg) Attachments ---------------- Table1Gen1MoparDoubleRockerEngineSpecs_Rev1.jpg (99KB - 184 downloads) | ||

Expert 5K+ Posts: 9911 Location: Lower Mainland BC | ' Just found these videos (couldn't find one for the 1952 Firedome introduction): Chrysler Master Tech - 1951, Volume 4-8 FirePower Engine Facts: https://www.youtube.com/watch?v=PBQ6ztwz_ac And Chrysler Master Tech - 1952, Volume 5-11 Dodge Red Ram V-8 Engine: https://www.youtube.com/watch?v=4jnNNQhZSJg The Dodge one talks about the compression ratio of the first Red Ram being 7.1:1 (Weertman said 7.0:1 in his book). The 53 Dodge Brochure says 7.1:1 so I guess Weertman was wrong? And this: Edited by 56D500boy 2021-03-28 5:48 PM (LosThreeAmigos.jpg) (1953DodgeBrochurePage6.jpg) (1953DodgeBrochurePage4.jpg) Attachments ---------------- LosThreeAmigos.jpg (61KB - 170 downloads) 1953DodgeBrochurePage6.jpg (235KB - 167 downloads) 1953DodgeBrochurePage4.jpg (188KB - 167 downloads) | ||

Expert 5K+ Posts: 9911 Location: Lower Mainland BC | . A bit of an update. One change is the compression ratio of the 1953 Dodge Red Ram double-rocker engine. Willem Weertman, in his book, says 7.0:1. The 1953 era Dodge brochures and videos both say 7.1:1. I changed the ratio to 7.1:1 for the 1953 Dodge Red Ram on that basis.
