New Project '65 Cuda - Gonna need lots of advise

Just picked up this 1965 Barracuda. Bought it from the original owner who said it ran fine before she stopped driving it about 6 years ago. Had it towed to my house because I didn't want to risk trying to turn it over and damaging something. My plan to start is to drain all fluids and replace, then pour some marvel mystery oil into the plug holes to loosen up the engine and try to get it started. it's a 225 with no ac. Be patient, you'll all be getting a lot of questions!
