Re: [Chrysler300] Radiator core fins on 300D

[lettercars@xxxxxxx]

Keith and All:
I think I can shed some light on the "straight fin" vs "squiggly fin"  
radiators.
According to the Engineering Data Books, published by Chrysler, (6/57 and  
6/58) there were four radiator vendors in 1957 and 1958: Blackstone, 
Fedders,  Modine, and Long.  Only the first three were ever used on the New Yorker  
and 300s.  Blackstone and Modine utilized the "Fin and Tube" design and  
Fedders used the Cellular Tubular (CT) design.  (The "squiggly" type)
 
For 1957: Non-A/C cars used ether Blackstone (2.5" thick, 9.5  fins/inch); 
or Fedders (2.25" thick, 12 fins/in.)
               A/C  cars used only Fedders (CT type) @ 2.5" thick, 12 
fins/in.)
 
For 1958: Non-A/C cars could use the Blackstone, (now 2" thick, 11.5  
fins/in) or Fedders (2" thick,12 fins/in)
               or  the Modine (2" thick, 11.5 fins/in.)
               A/C  cars used only Blackstone, (2.5 in. thick and 11 
fins/in.)
 
IN SUMMARY (Finally!): 1957 and 1958 NON A/C could be EITHER tube and  fin 
or CT
                                     1957  A/C would be ONLY CT 
                                     1958  A/C would be ONLY Tube and Fin
 
I can only hope the above is remotely understandable when in List Server  
form.

I just  had a beautiful re-core done on my C - not cheap at $575 - and 
replaced my  very original "straight fin" one with a virtually identical 
new copper  core.  But then that's for 1957.  In that year only one 
appears  to have been used in both A/C and non-A/C cars - 1686456.

But for '58  two different numbered radiators than the '57 are shown 
depending on  whether the car came with air or not. Yours is for the 
non-air  application,  Maybe those other cores you saw were the 1754875 
for  air cars.  And maybe someone can verify whether that one had the  
squiggly fins instead of the straight ones.
