Sikorksy UH-34D Sounds Like a Pickup Truck

[+Wrench]

sounds like any other WW2 radial to me! (at least it's not a Ford!)

[+Erik]

Ahhh yes and what a beautiful sound it is.

 

 

[+Muesli]

Damn... I love aircraft piston engine sounds!

[Trotski]

Yeah radial engines always sound agricultural,  especially on warm up.

I certainly hear the radial in it now. Early the first time I watched it though it did (still does a little) sound like an old diesel firing up. It still amazes me how aviation technology improved over the years.
