Well, I've spent more time, today, than I care to admit, (or
type-about!) researching the relative
'merits' of the 56 D-500-1 & 57 D-500-1 (aka: D501).
Right now, I need to find out how much more a 354 Hemi would weigh, than
a 325 Hemi.
Motor Life (5/56) tested a "340" H.P. 300B, with
9.00:1 c.r., and 3.36:1 rear end, and recorded
a 0 - 60 time of 8.0 seconds, with TorqueFlite.
The D501 was "lighter", had a MORE powerful
engine (57 300C carbs& intake, Trucker free-
flowing manifolds, 10.0:1 c.r., lighter valvetrain (58 fulie
intake valves) and possibly a hotter cam (I'll provide 'stats', below,
WITH an optional camshaft available, too), AND a rear end ratio of
3.73:1 !! That ratio allowed a 1/4 mile in only 2nd gear, maybe? Did
the "B" have 7-leafspring suspension? I knows it dint have no T/bars!!
Anyway, the standard camshaft (here you go, Dave H.!) :
Intake Opens: 35 BTC; Closes: 65 ABC
Exhaust " : 65 BTC; " : 25 ABC
Intake Lift : .444
Exhaust " : .435
Optional Cam Specs:
I. O. : 33 BTC; Closes: 71 ABC
E. O. : 68 BTC; " : 36 ATC
Intake Lift: : .394
Exhaust " : .400
In a letter to Lee Smith (1/2/68[!!] , from Chrysler, an attachment
lists parts-numbers
for various D501 components, including the following , for "Special
Intake Valves":
exhaust valves: 1634744
intake valves: 1821241 --that's a LOT higher
number!!--but Lee
was 'looking' for a replacement valve, & "this"
valve MIGHT be one that 'interchanges' with the original-valve..
btw, the 56 D500-1 had 10 optional rear-ends; the D501 offered 13 of em,
from 2.92 - 6.17.
Both 56 D500-1 & D501's offered automatic transmissions, but the
standard 56 'rear' was
the 2-speed PowerfFlite w/a 3.73:1 ; the 57 was a T/Flite w/a 3.18:1
standard (lotsa torque). Funny thing is, absent a H.D. manual
trannie--like from a 37 LaSalle--, the D501 was "better"-off with an
Imp/300 T/Flite !
But wait, there's more.....
