77 Roadrunner
I think the superpac cars included the 360 4bbl. You should be able to tell from the vin if it had a 360 from the factory. It really depends on how nice it is for $4500. I like those cars, My parents went to the Dodge dealer back in 1978 and had it narrowed down to two cars. A 78 Aspen Super Coupe or for the same price the new 78 Dodge Omni 4 door. That's to Carter's management we got a shiny new Omni! My parents keep things immaculate too that Omni sold 15 years later in beautiful shape with about 80,000 miles for the amazing price of $700. Should have got the Aspen!
