Re: [FWDLK] The Testies......



Hey, John; no, no attack at all!

Scientific inquiry demands close vetting.

This is what Hot Rod (5/56;p. 26) has to say:

"The standard sybchromesh sideshift gearbox used on D500's  is a heavy
duty unit with the following ratios: R: 3.2, L: 2.5, 2nd: 1.68,
High-Direct [presumably: 1.00]. These ratios have been used on all
Chrysler products for many years and one would think that for a gigh
performance car, more compatible intermediate ratios would be used; say
about a 2.3 Low and a 1.3 second But, alas, ! Such is not the case."

SO; You're RIGHT; I was looking at only part of the story; and those
numbers had merely jumped-out at me!


HERE WE GO: from earlier on Page 26 : 

"The D-500 gear ratios, mechanical pushbutton layoiut and 'kickdown'
feature are identical with the Plymouth, except the maximum converter
ratio at stall speed, which for the D500, is 2.71 @ 1850rpm..

And:..." D500 Powerflite had shift points raised somewhat for better
performance. Full throttle  shifts from Low to High  in Drive  were made
at about 70 mph, instead of about 55 mph for standard Dodges."

So, go plug THOSE numbers into your confusers!!!

So, the 1956 CRL 2-dr HT D500 with 260 "advertised" horspower, but 132

7.60x15" tires had virtually the same o.a. height as the 8.50x14" 1957

and 3.73:1 open rear end.
hi neil..
 
out of curiosity... how was second/final gear in the powerflite not a coupled 1:1?  did you pick up on that? theres no secondary planetary set in there to accomplish that, i dont think at least... the direct clutch couples the input to output shaft, thus a "straight-thru" from converter to yoke....
 
not an attack!!!!
