Train and Brakes
The
original Shelby 427 used
both
the
427 Side-Oiler and
the 428
Cobra-Jet
engine during its production run. The Side-oiler is rare - and much
more
expensive than the 428. It can be recognized only by
subtle
block
changes Ironically, the NASCAR
427 had only one 4bbl carburetor, while the
street 428 had
two.
How
about twin Paxtons!

Above: Here we see
how a customer can "go off the deep
end!"
This is a 427 engine with gold-plated Weber
carburetors. These carburetors are quite
expensive - about
$3500
for the non-gold-plated variety - but they do look good. They
also
CAN run good, but it frequently takes quite a bit of twiddling to get
them
right. |
We also have mounts for
small block and 429
Ford, and small and big
block
Chevy.
You can see the aluminum
firewall
with all the electrical components in back of the engine.
The E.R.A.
hydraulic
braking system is designed for
maximum safety,
efficiency
and balance. The complete brake hydraulic system, except for the
calipers,
comes installed
on the standard
kit.
Both the illustrations at the right are taken from the assembly manual
This includes:
- Dual
Tilton master cylinders connected
by
an adjustable balance bar
mounted
under
the floor.
- All brake
lines, both
steel and flex,
mounted on the chassis with insulators at intervals that will make your
state
inspector smile..
| | The
emergency brake system works
surprisingly well on both the Jaguar-based rear suspension and the ERA
design. In both, we've made the proper mechanical advantage
so
that it it takes neither a monumental pull on the handle or a too-long
stroke. Both systems are self-adjusting for pad wear. | |
| - The
pedal
system includes all pedals arms with
pivoting
aluminum pedal faces (see
below)
with "ERA" or "AC". We support the hardened
pivot shaft and the brake pedal in needle
bearings.
Like the original car, the pedals are
pivoted
underneath the floor.
Unlike
the
original car, we protect the master cylinders in a box (not
illustrated)
that is removable for service.
All stress bearing parts are mounted directly
to
the chassis.
An
adjustable balance bar
connects the
master cylinders with the brake pedal.Dual
brake light switches with dash warning light for hydraulic
malfunctions.
Optional
remote reservoir on
the drivers
footbox. |

GM-based 11" x 1" vented rotors and floating calipers (shown
at the
right)
stop the front. Special
larger
brakes are available for racing or
heavy duty street
use.
In the rear, the standard Jaguar-base inboard 10.5"
x .5" solid
rotors are
clamped by Girling calipers with separate emergency brake caliper.
Our optional
rear suspension
uses 11.75"
vented rotors clamped by PBR floating calipers with integral emergency
brake
function. |
|
The complete
hydraulic
clutch release system
is included
in
the kit, with all but the slave cylinder and connecting line installed
on
the chassis. Also included is a slave cylinder bracket and the
adjustable
link to the throwout fork. You just bolt the pieces in. All
brake
and
clutch lines (including the flex hoses to the calipers) are installed.
Also
installed are the clutch pedal, master and slave cylinder; fuel tank,
cap,
filler pipe and lines. |

Our custom
aluminum
radiator (with electric fan)
is the
largest
in the business and fully shrouded in aluminum. The standard fan will
cool
most big block street engines in temperate climes. Order the
optional
fan if you have a big engine and live in an un-naturally hot
envirornment,
like south of Connecticut...
| Our throttle
linkage
mounts on the footbox like the original
car and lets
you bolt up to most 4 bbl carburetors directly.
Except for the engine bracket, all pieces are installed on
every
car,
even on our standard kit. Note that the engine-end pivot is mounted on
the engine itself. This prevents engine movement to feed back
(sometimes unstably) into the throttle position.A: Pedal B:

We
also can supply the engine linkage and bellcrank for twin 4 bbl
carburetors as used on the original 428-engined Cobras (and retrofitted
to
many 427s). |
