Jim,

   I'm sure it varies by location in the country, but in 
the PHX area, $400 for a running engine is about par.  
$250 for an unknown core seems a little high, but maybe not, 
if you get *everything*.  

   I paid $200 for my first block, but it was missing the 
secondary injectors, flywheel and even the counterweight.  
They didn't even leave the big nut.

Dale R.
