Ron, if you are asking about the 1957 D501 models: all of them were manual transmissions. Dunno about the 1956 D-500-1 models, as far as their trannies are concerned.

Dodge did the same thing on the 1958 Dodge D 500 super with 2/4 bbl carbs.(same cam)* *However I do remember reading a special report on the 1957 D 500-1 which had the leftover 56 Chrysler 300 B engines of 354 cu inches, it said they had the new 1957 Chrysler 300 C cam with solid lifter installed in their 354 engines.* * I wonder if anybody on the list knows if there were any D 500-1 that were produced with Torqueflite transmission. Nobody seem to ever talk about that?* ** * Ron Swartley** (still loose on the East Coast)*In a message dated 12/10/2010 2:41:35 A.M.

Like – for instance and among others – Generator Bracket, Shaft to Carburetor Rod and Coil Mounting Bracket. So, not listing a Super D cam doesn’t mean there wasn’t one. But like I explained earlier: the ‘basic’ D500 was capable enough to handle the increased air/fuel mixture flow at higher revs. And the higher revs were simply and solely accomplished by adjusting the transmission rod to a higher shifting point. Higher revs need more air/fuel mixture, that’s when the second (front) carburetor comes in. In contrary to the 1956, the 1957 Super D dual carburetor setup was progressively linked.Jim, The Netherlands.************************************************************* To unsubscribe or set your subscription options, please go tohttp://lists.psu.edu/cgi-bin/wa?SUBED1=l-forwardlook&A=1 <http://lists.psu.edu/cgi-bin/wa?SUBED1=l-forwardlook&A=1> ************************************************************* To unsubscribe or set your subscription options, please go to http://lists.psu.edu/cgi-bin/wa?SUBED1=l-forwardlook&A=1
