When speaking about bigger spark, one needs to understand I do have a hotter than stock spark with my points setup. If your ignition resistor is say 1.5 ohms measured with a multi-meter, change it to a 1.2 or 1.3 ohm resistor. That little difference will increase the voltage to the primary side of the coil, which increases the output, but will not hurt the points. Okay, you may need to replace points at 12,000 rather than 15,000 miles...Big Deal! Add a better coil, say ACCEL 42000 volts street coil, use the best available (BWD Select) points, condenser, rotor and cap, then get the best (lowest resistance per foot plug wires) and use the best platinum plugs gapped a few thousands more open...and hello bigger spark! More power? Maybe, but probably not something you can seat-of-the-pants feel. Better starting...yes. Better MPG...yes. Cleaner running engine...yes. ALL with updated points. I used points ignitions for 50 years using these slightly hotter spark ignition ideas, and it works. Remember, you need oxygen to burn fuel, so a good, even home-made cool-air intake helps. Increase spark, blend in cooler more dense air, time everything properly, make the fuel as gaseous as possible (Autolite 2100/4100 carbs with annular atomization or newer Holly) and unless you expect to go racing, you are good to about 5,500 to 6,000 RPM. The pix's are my 65 Mustang 6-cylinder in Oklahoma, Tennessee, and my shop in Texas. It is a driver and the LH-6 on the hood stands for Long Haul 6 cylinder. Running the AC and getting 25 mpg on the highway without overdrive. A fun six-banger!
