A properly tuned engine that has a rough idle does not have the correct fuel and air mixture at low RPMs. The rough idle is cause by poor burning of the air fuel mixture. If you cause your car to run rough to look like you have a lot of horse power, your foolish. Your giving up what your trying to advertise. Yes there are plenty of large cam street cars running around, but if they are not properly tuned to have the correct air/fuel mixture for the used power range, its only a matter of time before they need to be rebuilt. It may be 2,000, 10,000 or 50,000 miles. It won't be the optimal engine life though. Ask a reputable engine builder. I would be surprised if he recommends a poor tuned engine for a cool sound.
