I think it says Magnum on the hood. I ran the tape back several times to try to read what it said but couldn't tell for sure. However, the lettering appears too long for just Hemi. Also, at idle, it sounds like a 440.
Something to note. Most of the time, the engine sound is put in at post production, so you never know where they got the engine sound. It can be from anything.
