Engine Drama.The Nova wore the orginal 250 emblems on the fenders above the turn signals when my father purchased the car, meaning at one point possibly originally out of the factory this Nova had an inline straight six. When purchased, under the hood sat a small block chevy, a 307. My dad took the engine to get looked at by a mechanic due to the timing cover not being able to be placed correctly back on by him. The car stayed at the shop for some time, got the power steering fixed, minor leak, and some oil leaks fixed. Then the engine was taken COMPLETLEY apart down to the block. For a "rebuild". In exhange for the small block to get fixed my dad put down some money and got a big block out of a chevy truck dropped in while they are to finish up fixing the 307.
