Here's where people get clouded. "I want it to sound good"

Throw that chit out the window. Any high performance engine will sound like one. Put sound completely out of the picture when choosing parts. That's how you tell bench racers from real car guys. Choose parts that will work well for your car's weight and its intended purpose. As long as you do that, It will flat out haul *** and be fun.
