BARN FIND Pontiac Star Chief, will it RUN after 42 years?

Today we work on a family heirloom car. This 1957 Pontiac starchief is a single family owned car since new. My friend dans grandfather bought it brand new in Iowa in 57. Now it’s sat for 40 years. Will it run now after being abandoned in a barn since the 80s?
