Here is a peek at that 390ci V2 280hp engine under the hood. Well, this looks like it was changed to a dual carb setup. Most 390ci engines got the 4 barrel carb, this one came from the factory with a the 2 barrel version. It's an X code engine. The VIN has the X in it - 8R01X164476. It says "Old School" on the underside of the hood.
