Easy? You're supposed to take it easy? After our Miata suffered 
catastrophic crankshaft failure in 1999 I put in a new long block from 
Mazda Competition Parts and told the wife:"Don't drive it below 3,000 rpm 
and try to keep it around 4 to 5K." Now it has 5,000  mostly street driven 
miles on it and has had Mobil 1 since 100 miles. Rob Ebersol, who has been 
racing MIatas for years says that street driving is the best way to break 
in a new engine. The thing to avoid is running at high rpm for extended 
lengths of time so don't use the cruise control on the way back to KC.
