I think someone was trying to make these give-a-way cars, HEMI cars. They are there at the event in mid-February of '64. There were NO HEMI drag cars at this point (maybe a test mule or two, but none of the production cars) let alone street cars to give to the top Mercury driver. From what I hear the DAYTONA 500 (same month - ran 2/23/64) was the big prize and getting enough engines and parts to Florida was a priority. The Daytona 500 is rumored to be the reason that a HEMI never made it into the Charger I show car. All the press and promotion for the car said it had one, but I don't think there is any evidence that it actually ever had a HEMI.
