The mods in the JP mag article include improving intake and exhaust flow, and replacing the power robbing belt driven fan. They did not improve the ignition or fuel systems. It seems like they only did part of what is needed to balance all the engine components. I have installed the same set-up, except my Taurus e-fan is still in a box. I have an Accel multispark CD ignition and FoMoCo 19# injectors that will go on soon, along with a DIY map adjuster.
Based on my experimentation so far, I'm convinced that regearing to match your tire size is the most important performance mod.
