First off my wallet is far from fat,i just know where to invest my money and time to get the best results from my 'street' car ..no strip only car here!!..Secondly i was doing cam swaps and other motor work on 340's back when i was 15..and was a mechanic for 15 years before switching jobs i just don't have the place or equipment to be doing my own motor work now,so i pay top notch people too do it for me,that gives me the piece of mind its being done correctly,,as for the new challenger if people think 13.1's are quick you'd probably have a heart attack if you ever drove a "real"car...:-D
