nothing wrong with solid wire and electrically it's actually better if done right. however, having said that stranded wire will not usually break because of vibration which solid wire will do, like a paper clip bent back and forth it will break at some point.


Some friends that run a sprint car had a similar goofy problem, make sure the distributor body is also properly grounded as the gasket will act as an insulator. You cannot have too many grounds, the more the better, including block, heads, intake, AND distributor.. and use the biggest wire you can physically get away with as modern ignitions pull a **** load of current. 12ga or bigger!
