A 460? Well, certainly a pretty stock 460 is going to be pretty quiet next to a somewhat "warm" smallblock such as mine.
Just kidding...sort of. The sounds are all different based on the motor. I'm running a fairly stout cam (about the biggest "Street/Strip" cam from CompCams in the hydraulic cam dept.) and at idle, it's just got a really cool lope. You can't so much hear it in the house as you can feel it.
At WOT, you can hear it well over a mile away. Probably several. Especially in 3rd gear at 6K+ RPM. And it sounds good.
But that same car, I can idle through the neighborhood in 2nd gear at night and it doesn't get noticed too much. You eventually learn to drive them nicely.
Harleys have that "pop" to them and as they wind up, the "popping" gets faster. The sound never really comes together as a pitch to the human ear. The cobras do. When you open one of them up on the road, you can match the pitch with a loud, lung bursting "WWWHHHHHAAAAAAAAAAAHHHH".
A BB or SB that is built up a fair amount (big carb, big heads, big cam) will sound like a race car through the sidepipes at WOT. A crate 351 is going to sound like a really wild Mustang 5.0. A crate 460 will sound like a Ford School Bus.
Just kidding!!
Your car will make you smile, make your wife wrinkle her nose, and have similar effects across the gender lines in your neighborhood. Enjoy it!!!
