One of  the reasons you can get 200-300K miles on engines today 


There have been several comments recently on VV about Corvair engine  
longevity.  Realizing that our engines turn at higher RPM than today's cars  
which have overdrive, 2 to 1 diffs and computer control so they  should last 
longer, but I still had one smog engine that went just about 200k  before 
something broke (haven't torn it down yet so I don't know what broke  yet--and 
because it is a smog engine and I have too many projects already I may  not 
rebuild it).  Another smog engine went 127K before it dropped a seat.  My 
Greenbrier has about 130K (I'd check but it's under 37" of snow from  our last 
two storms) and runs strong never having had any mechanical  faults.
 
Just what is the collective experience for engine longevity that others  
have had?
