How far to go 383

14 years is a long time.. have you been "taking care of it"? ..have you tried to turn the engine via the crank shaft? I would take the heads off and have a look at the cylinders. If you are adverse to doing that, at least get a crank shaft bolt on there and see if she'll turn for you. If it doesn't, I had a friends who did this years ago: put some Marvel Mystery oil in each cylinder and let it soak for 24 hrs. - try to turn the engine again - - repeat as often as necessary until you can get it to turn easily...
