No, I have not had an estimate. I was wondering if I could buy the exhaust system from one of the chevy parts stores. Since this seems like a common swap, I was wondering if I would have to take it to a muffler shop. I have a 235 in the PU now but it has 216 manifolds and a Carter W-1 carb. I would like to find some 235 manifolds (54 or latter) and a corresponding carb and hopefully improve its performance.
