Whiplash cam. Your thoughts
Now I know not to choose a cam for sound. I explained that earlier, but how often now a days are we actually "ripping around the streets" and racing. I think you misunderstand - the loss of raspy sound is accompanied by a better throttle response and low and mid-range power. This is the real power you will use every day - racing or not.
But when I wasn't racing, who cares it sounded like a kitten. We all like a bad bass sounding car, we all love lots of power. But I'm gonna hear my car and be cruising it more then I'm gonna be racing it.
I bent custom exhaust for a while when I was younger. A good exhaust guy can taylor the sound so even a smooth running engine sounds bad ***. I had a Dart with a bone stock long block 383 with a small purple shaft in it that sounded amazing even with full stock type mufflers. If it's sound and attitude you want, get it from the parts that make sound.
Just because you want a nasty sounding motor. Dosent mean you haven to sacrifice power. Hell, lots of my friends cars sound amazing and there fast and powerful! I agree - fast and powerful is cool, sounding wicked is cool. But as you noted you will not be at full throttle that much. So IMO the approach is to get the right sort of power for you, and plenty of snap when you are full throttle. The guy next to you at the light will be looking at the car anyway.
