I have a 1968 Firebird 350 convertible and I am thinking about getting the engine rebuilt I have a budget of $4,500 to $5,500. My question is how much it typically costs to rebuild an engine and if I am going to restore the car is this a good first project. I am going to take the car to a local (I live in Pittsburgh) guy who rebuilds engine and he said the range is between $4,500 and $7,500 depending on how custom the job is. Any insight or feedback would be greatly appreciated.
