after a long search, i've located 2 potential 200 engines. 1 is 3 hour away that has 5000 miles on a professional rebuild. the crank was turned down and the cylinders were bored on the rebuild. it has not been ran since 2001. its complete from intake to pan. it is a '65 block with a '63 head .the guy want $500. the other one i located is only 20 minutes away, has been sitting a long time. it is a '66 with no signs of ever being rebuilt and no ideas of mileage. i can get this 1 for about $100.
