If I remember correctly, one of the cars was a 1970 340 4 speed car. That was the close up car. One was a 70 that had a 440 in it for the high speed shots. One was a 71 318 Barracuda ,and the one that they blew up was a 73 318 hardtop with the roof cut off it. I read an article about the 4 cars used in the series. The listed the VIN numbers of the cars. The 70 340 4 speed car was the only real Cuda convertible. There was no mention of any of them having 360 crate engines in them.
