I understand NASCAR engines are built precisely and with everything fitting tightly and exactly. However, rather than producing 800 hp if building a 600 hp street engine what are the main points that get you close to the sound out of a small block? I've heard two small block Mopars on the street that have that NASCAR sound. One of the cars was a Challenger I think Hotchkis had on the Power Tour three years ago.

When did NASCAR require mufflers? Nascar does not use mufflers They use "Boom Tubes", not mufflers
Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

The current set up makes for a good street/strip car that has provided years of reliable service but when I am pulling through a crowded cruise-in and people walking in front can't hear me coming through that is frustrating. Just struggling with a coming up with a new identity for this car.

Lengthy video, but they take this car for a test drive at the end and it sounds pretty serious. You'd have to be deaf to not notice it. https://youtu.be/kpRwmFo431c Yes I agree. I like what they have to offer. Side exhaust is wicked cool and the sound would be like nothing else around here. Could be the end of date nights in the Charger to the big city with the wife but I doubt she'd care.

14:1 will put some snarl in it at 8500 RPM.
Kevin cup cars are 12.5 to 1, unless they've gone back up to 14... 9500 rpm and long, straight tubes are a big part of it, i would think.
for what is the good life if not doing things thoughtfully?
