big block chassis car headers

they wont fit with the inner fenders.. as far the front it will have to be a tubular k frame or strut front end ( i think) and i say i think because if i cut a few tubes and reroute them they will work on my car ..but to me i would like my collector and pipes inside the frame rails tucked under the car...this will be outside the frame rails like a fender well header...they are 17/8 in size...hope this helps anymore ??? just feel free to ask dont wont to sell you something that dont work for you.. mike
