Chrysler I doubt would have been so dumb to make the early 6V 300s  poor/slow 
crankers from new - Chrysler of all the US carmakers/majors were  mainly 
engineering driven, unlike say GM who after the late 50s maybe too  often let 
the bean counters carry too much weight sometimes  !!??

Anyone out there remember these cars new - surely they cranked  pretty good 
new, even if 6V ?
 
 
Response:
Yes, I, at least, remember.  As some may recall, I worked in the  Fuel 
Systems Lab at Chrysler Engineering.  We spent lots of our time  doing "hot start" 
and "cold start" testing.  Hot start tests were done on  the road by parking 
alongside the road in the sunshine for 15-20 minutes after  high-speed driving 
for several miles.  We looked for fuel bowls to boil  over through the vent 
tubes and flood engines, making hard-start  conditions.


 
Cold start tests were done by starting as many cars as we could stand to  in 
the early mornings, and immediately driving them around a standard two-mile  
test course, stopping every two blocks and alternating part-throttle with  
wide-open-throttle  accelerations.  (I hated that!  Scrape the  windows of ice, 
then drive the course, recording data over-and-over, and just  about the time 
the heater started working, park that car and get into  another.  B-R-R-R-R!)
 
We tried very hard to engineer them so that they would start and drive  any 
time, anywhere, without any special techniques beyond the basic "Step on  the 
gas pedal one time and release it to set the choke.  Do not pump the  
accelerator."  "If the engine appears to be flooded, hold the accelerator  all the way 
down and crank the engine to clear the flood."
 
Of course our engines were always fairly recently tuned up, though not on  
any particular schedule, and always in good condition.
 
I have no idea what modern fuels might do to aggravate starting and fuel  
boil-over conditions.
