the 408 is just going to be toy, hit the streets, and track i doubt if the car will see 2000 miles a year Im looking for a very healthy very nasty sounding sb. the car is a 4spd and im not too worried about street manners as most of my cars dont have much for those. I love th sound of the thumpr cams but there performance is terrible, id like to have my cake and eat it too.
