This what I was told by the owner: the car was bought new (1 owner) as a formula with the SD 455 engine, the car does have the shaker hood, I never looked at the engine, but I will. Is this possible???you need to look at the engine code stamped in front of the passenger side cylinder head on the engine block. It will be a letter code like CH, HFG, etc. The formula did not have a shaker hood, it had dual scoops on the hood.
