When it comes to any upgrade it is whatever floats your boat. I went to the slant 6 electonic for the much hotter spark, no radio interference. and no points to wear out. But that is me. The car manufacuers went this way for a reason..I can cruise all day long at highway speeds and the engine does not skip a beat. ( did before ). My spare parts kit consists of only a fan belt. The car is set up very much like Dons except for engine size and rear ratio, and will go where ever she is pointed. Hot August Nights in Reno this summer (2013)
