    I’m working on my Dad’s ‘64 GT.
    What is this thing on the firewall I’ve circled and what do I need to do to get rid of it?
    I want to put the coil back down on the intake manifold where it belongs.

    That is the ballast resistor. Put it down on the manifold along with the coil.

      The Flamethrower Coil could be replaced with a correct one and mounted properly on the intake Manifold, but you need to find out WHAT you have for a Dist.

      It is likely electronic or has a Electronic, Pertronixs Brand Unit in it that does require a 40,000 Volts or more Coil.

      Does the Car run OK?

      If the Ignition wire to the "Ign" Terminal of the Ign. Sw. does run THROUGH the Resister to the Coil, you may only be getting 8 or 9 Volts to the Coil, if you bi-pass or remove it, you will get the full 12 volts, which may be good depending on the Distributor System you have.

        Yea its a ballast resistor, follow Stude Rich's advice. this item can and will cause some maddening problems down the road, dont ask how i know. a Pertronics unit needs full Batt voltage to work properly. Luck Doofus

          If it has a pertronix setup.

              I recommend using a ballast resistor with the Pertronix coil. I don't care what Pertronix says about using their coil with 1.5 ohm primary winding resistance and no resistor. I've had several of their coils fail due to over voltage which causes overheating and eventual failure of the coil. If a ballast resistor is used, the output at the coil will drop about 5 kilovolts which will not be noticeable on most Studebaker engines. Actually the coil being mounted on the firewall is better for the coil as it doesn't absorb heat from a hot manifold, though it doesn't look as nice. The Pertronix module does need full voltage to function correctly so do not connect it to cold side of the ballast resistor. Bud

                Some truck models had no mounting bracket on the manifold and the only option was the firewall, I don't know why?Click image for larger version

                  It's a TRUCK! Trucks were expected to be like Police and Taxis, they COULD be subject to long periods of Idling and more so, heavy Pulling, and Hauling which means MORE HEAT!
                  Which is also why they had Low Compression Heads, not only to run on lower octane cheaper fuel, but to reduce heat.

                  There is a reason Studebaker had a very complete, well used and effective "Proving Grounds".

                  The Firewall is a cooler, better location under those possible conditions, especially the Large amount of Ton, Ton and Half and 2 Ton Farm Trucks Studebaker sold.

                    The car does have a Pertronix module. But I can’t for the life of me remember why my dad had this done with the ballast resistor. I’m very sure someone did this for him since my dad was no kind of mechanic and certainly wouldn’t have fooled with the electrical system. The car hasn’t run for close to 2 years now, the last time I was here. Thankfully I have my ‘63 GT here now too and can compare it to mine to get it correct again.
