1) If you continue the use of mechanical points, which its not best to switch much over 4 amps of current, the Flame Thrower or Accell Or Super Coil or Super HV Coil or the Billy Bob Special Super Super Coil, or the factory stock coil IF ALL ELSE REMAINS THE SAME (compression and fuel) WILL NOT YIELD MUCH IF ANY GREATLY MEASURABLE DIFFERENCE IN PERFORMANCE AND THE FIRING VOLTAGE WILL REMAIN THE SAME REGARDLESS WHICH COIL IS USED !!!!!!!!!!!!!!!!
2) If you use any combination of coil plus ballast in the primary ignition circuit that has a total resistance a lot under 3 ohms (for a 12 volt system or half that if a 6 volt) and you still use points, THE POINTS WILL BURN UP SOONER AND IN TIME THE PERFORMANCE WILL BE DRASTICALLY REDUCED !!!!!!!!!!!!
3) Iffffffffffff the flame thrower has a primary resistance in the neighborhood similar to the stock coil i.e. around 2.5 to under 4 ohms (for a 12 volt or half that if 6 volt) you can use it unballasted in place of the stock coil and the points will last about the same and performance will be about the same NOT ANY PROBLEM
HOWEVER if you combine a high energy coil with an elec switch that has the capacity to switch the coils current IT IS POSSIBLE TO DISCHARGE A SPARK GAP WITH HIGHER ENERGY THEN THE STOCK SYSTEM AND "POSSIBLY" GET BETTER PERFORMANCE
BOTTOM LINE Be careful of HV after market coils use on a stock points system as if the point current is greatly increased they will burn and carbon sooner and performance will be poor pretty quick I.E. CHECK THE COILS LV PRIMARY RESISTANCE needs to be around 1.25 to uncer 2 ohms for a 6 volt system (or if on a 12 volt with an added ballast) or 2.5 to 4 on a 12 volt system......
Those high energy coils are more for elec switch use that can handle their higher current, they can still be used with points if their resistance matches the stock coils so the points dont burn up prematurely but if they cause the points curfrent to rise dramatically the poinst will burn caRBON AND performance will go real bad real quick
