interesting car craft article this month on GM modules

Now before you go all crazy over me talkin Generic Mortars, there was a carcraft article about converting your mopar or ford electronic distributor to run a GM HEI module. This isnt a DUI type distrubuter for mopar or ford with the big blocky cap, rather its a way to use the small GM solid state 4 spade module to run a ford or mopar stock electronic distributer, instead of using the big blocky spark boxes both are known for. This will clean up the engine compartment. Theres even a really neat billet aluminum mount for it on the mopar distributer somebody online makes for a few dollars.

Any advantage to doing this? Disadvantages,? Im not a purist, unless its a rare numbers car. In my current buildup am into bang for the buck. Will this work just as well or better than lets say a nicely setup mopar distributer with an orange box.

Id prefer to hide the unit, than to display a big honkin sparkbox, but will use the big honkin sparkbox if it has an advantage.
