Ok, just want to know if the engine sounds for this movie Mopar are the real deal or did they dub something else in? Sounds like my E body 4 speed. What do YOU think?
The quick answer is "sometimes it was" - and sometimes, it wasn't.
Do a GIS (internet search) for an article titled "Kowalski's Last Ride" that originally appeared in Musclecar Review
magazine in 1986. In that article, the movie's director as well as Barry Newman himself answer a lot of trivia
questions about the movie firsthand - as does the stunt driver/coordinator on the film.
You'll find out things such as there were (5) Challengers used - (4) R/T 440 4-speeds and one 383 auto.
You'll also discover that some of the same sound effects used in Bullitt were used in VP - and the thing to
keep in mind with Bullitt is that the Mustang engine sound effects were not from that 390 Ford, but taken
from the original Ford GT40 car!
I actually feel some empathy for those who say "all V-8s sound the same" because that's simply wrong,
in much the same way as Led Zep doesn't sound exactly like Clapton or like Black Sabbath.
Same "job", using essentially the same "hardware" - but VERY different sounds.
