Why do Mopar Engines Have a Different Sound From Chevys and Fords??

Compared to what?

All the later Mustangs that blast up and down my street sound exactly the same, I don't even have to look. :banghead:

And then there's the different engine designs. Old Ford flathead V8's have a very particular sound. So do the FE block Fords for that matter, thanks to the 390 in my g/f's '71 F100 I can tell when something has an FE in it just by listening. And of course NOTHING sounds like a Hemi. :D.

And if you want to leave V8's behind, all those pancake 4 Volkswagon engines have a VERY distinct sound, regardless of what's been done to them. Same with the new Subaru "boxer" design engines.

Differences in the V8 designs are more subtle (except for the hemi's and flatheads), so the differences in sound are too. But its my experience that any family of engines, LA, B/RB, etc will have its own distinct sound. And that can carry over to the entire make, since its usually all the same folks designing the engines. It would make sense that old mopars would sound like old mopars, old fords like old fords etc.
