Why do Mopar Engines Have a Different Sound From Chevys and Fords??
Compared to what?
All the later Mustangs
And then there's the different engine designs. Old Ford flathead V8's have a very particular sound.
. And of course NOTHING sounds like a Hemi.
"Later Mustang?" So now you are comparing a factory engineered PACKAGE of many changes, perhaps EFI, factory exhaust, etc
IF you were to take a LEGACY Ford 302, Mopar 318, and Chev 302, and build 'em as close as you can to the same, IE cam, intake, headers, you would lose a lot of money betting on which was which
"Hemis sound different?" Not a chance. Take a legacy 426, built to the same general cam, carburetion as a 440, with about the same size headers, and nobody will ever know
Flatheads? Completely different engine DESIGN, I "assumed" we would at least stick to typical modern overhead V8s and leave the 3, 4, 5 and 6 cylinder, as well as 12 and 16 cylinder engines out of the mix
BUT HERE'S the THING
Many of you have heard a couple of engines, and they SOUND DIFFERENT.
FINE. Do you know that they were built on the same level? Hell no!!!
All it will take for that BB huge ba BOOM Bah out those huge pipes to go away is "less pipes", less cam, less compression.
Ever heard the "Flying Yellow Brick" run? Doesn't sound like any Y block I ever saw phut-pha-phutting around town

Remember the "factory" sound of the 68-70 Super Bees, Road Runners, and GTX's?
Guess what?
You take those SAME mufflers, move them up under the car toward the headers, and bring the exhaust out in front of the rear tires, and they sound NOTHING alt all like the factory system.
On the factory muscle cars, it's mostly exhaust system design (with a stock engine build) and the design of the air cleaner. Snorkle, smogged up air filters will affect the overall sound opposed to an aftermarket open filter.
