I bought a 301 Shaker Y84 S/E 2 years ago for $2500. Been sitting for 6 years but ran/drove. motor was rebuilt before parked. I rebuilt carb and transmission pan gasket replaced. I went through the brakes, tires, hoses etc... then put a cheap paint job on it and freshened up the interior with new paint.
However, the car is not worth more than I have in it now, about 6K. There is a 55,000 mile survivor I saw for $12,500 and is near mint. I would go that route before trying to "restore" mine. Just can't fix them for less than that.
