Mark, I have duals on both of my cars. Here is my suggestion, call George Asche, send him your carb and he will build a match, set up for duals. Buy his carb linkage set up. EZ to install and looks great. I bent my lines with a common tube bender, but i did put the fuel block down by the fuel pump, out of sight. I have since upgraded to an electric fuel pump. From the what its worth department, On my 49 coupe, while I had the head off, we did a valve job, new valve springs, pulled the pistons new rings and bearings. You Will, start reving the snot out of Ruby! Have fun, cant wait to run the gravel roads of Vermont again. Those crazy Plymouths just took off!!!!!
