I’ve simply gotten my 1973 Challenger
operating. It used to be a 318 automated automotive, now I
have a 340 and 4-speed put in. I purchased
many of the portions used at swapmeets and
such, I’m on a decent finances.
One downside: The grasp pedal desires
to hold at the ground and no longer pop again up.
I’ve a excellent 3-finger grasp, and the entire
changes appear advantageous. Are you able to level me
in the fitting route?
Because you purchased combine ’n’ fit elements
from who-knows-where, there are
numerous imaginable areas of difficulty. My trained
wager is that the pedal meeting
you purchased got here from a 440 (or Hemi)
’70–’71 automotive. Those had an overly beefy overcenter
spring which decreased the pedal
effort with the robust grasp. I’ll suppose
that your Borg and Beck power position is
a normal smallblock model, with somewhat
pedestrian clamping load. The over-center
spring is most likely too robust for the power
plate springs, and holds the pedal to
the ground. There have been in truth 4 other
springs for various mixtures, those are
the B/E phase numbers:
APPLICATION PART NUMBER
340, 383 2950922
SLANT 6 3575119
318 2950921
440, HEMI 2950923
A few of these are extremely robust—
built of three/8˝ spring cord. One repair is
discovering and putting in the proper (weaker)
spring. The straightforward approach to try this is to have
an assistant depress the pedal to the ground,
and jam washers between each and every coil, then
unencumber the pedal. You’ll hammer washers
between the coils of the “new” spring
to put in. To my thoughts, then again, that is
all garbage. Ditch the spring completely, and
set up a excellent diaphragm power plate.
You’ll be amazed on the development.
