...Hello BoB! The Ballast Resister will have nothing to do with the Cranking 'Speed' of the Starter Motor. It (The Lack of a Resister) WILL have everything to do with the coil getting Hot enough to butn your hand, and distroy itself. The later Panteras My '74, Maybe '73's did NOT have a 'Separate' ballast resister! Instead they had a Resister wire (Solid Blue). Which, by the way WILL MELT (and the Coil will get very Hot), as in My case; if you have a 'Dual Point' distributor and One of the Point sets stays closed (never opens). Some heat IS normal for the coil, but never THAT Hot! I have since gone to an electronic ignition. NOW, to Your main question of slow cranking! The following comes to mind: 1. How old is the Battery? The connections (Posts and Clamps) must be Shiny Clean where they contact each other, and where the Cable goes into the Clamp, must be 'Solid' and secure. I recommend every New Pantera Owner, first thing, go out and buy the Largest Cold Cranking Amp Battery that they can stuff into the Battery tray. If it is over 3 years old, it is on it's way out! You can verify this by connecting a Volt/Ohm meter to the Battery and Observe the Voltage Drop through the windshield while you crank the engine. 2. You write that Your 'High Torque' Starter Motor is fairly new. I have 'seen', a couple of Brand-New Starters that were faulty from the start. 3. Very rarely the case! But if the contacts in the Starter Solinoid are Badly Burned, this could cause a lose in Amperage to the Starter. Again get out the Volt Meter and connect it to the Post AT the Starter Motor Itself, and Make Sure you are getting Voltage. How Much!? It Should not drop 'Much' below (if I remember right) 10.0 - 10.5 Volts while at Full Cranking. That's about all I can help You with. Good-Luck with it!! #5723
