Electronic ignition replacing the points with Crane products, for
Go to <summitracing.com> and search for Crane Cams
and order the XR700 part number crn-700-0231 FireBall points
conversion ignition kit, and from Pertronix buy the Flame-Thrower
coil part number pnx-40011.
Now you are ready to convert your Studebaker from points to
pointless electronic ignition. The first step will be to fine the
number 1 plug on the car and to check the engine to see that the
timing marks on the crank shaft line up on the timing marks and
that the rotor on the distributor lines up with the number 1 spark
plug wire. I put a dot of white paint next to the number 1
spark plug wire and took the distributor cap off to see for sure
the rotor was lined up with the number 1 wire. For the
Prestolite distributor on a v8 the thin walled shutter is used.
The thin walled shutter will mis the post where the existing
points are mounted. The shutter has no metal tabs to press tight
agents the cam lobs so take thin aluminum (about .005, most
hardware stores will carry this type aluminum in a roll about 12
inches wide and 2 or 3 ft long.) and cut four T shaped peaces and
slip them in four of the slots next to the inside cam lobs
on the shutter. There is a slot by each cam lobe. You can put some
contact glue on each T shaped peace to hold them in position.You
will use the FireBall XR700 instructions to replace the points and
add the electronic ignition box and the new Flame-Thrower coil.
The first step is to remove the distributor cap and the rotor
from inside the distributor. Now you are ready to remove the
points and condenser from the distributor. By using the thin
shutter for you v8, the post that the points are mounted to will
not need to be cut off the distributor plate. If
the electronic box would ever fail then the points could be placed
back on the distributor plate the you would be up and running.
This is a nice backup.
OK now with the points and condenser removed you are ready to put
in the trigger and shutter for the electronic ignition. You will
follow the Universal 4-6-8 cylinder distributor adjustable bracket
kit to install the trigger and shutter. With the engine still set
to the timing mark the distributor will also still be set on the
number 1 plug wire you can set up the trigger to fire at this
phisical location and your car will be timed correctly. When you
install the trigger and shutter rout the wires so they do not come
in contact with the rotor or the shutter.
I mounted the electronics box on the fender on the passenger side
of my HAWK, as there are two bolts that hold a brace on the
underside of the fender. I made a bracket that mounted to the two
bolts and i use 4 screws to mount the box to the bracket. The
length of the wires on the box will go from the box to the
firewall and then back to the coil that is mounted on the back of
the intake manifold.
Your old coil can be replace with the new Flame-Thrower and you
will be ready to set the trigger to the correct timing. There is a
LED on the electronic box that will come on when the trigger is
set to the correct place. There are very good instructions in the
FireBall installation manual. The trigger can be mounted any place
on the distrbutor plate as the engine is still set to the correct
timing marks from the work already done above. The
XR700 installation instructions are very good, If you have
