Ah the continiung banter of Quadrajet versus aftermarket. I have had a Edelbrock 1406 on a 350 for two years with little to no problems. You have to set them up for your general operating altitude--I followed their manual and it has been spot on and vary repsonsive. The electric choke does take some seasonal adajustment, but I live in Montana. Quads are good if the throttle shafts are not leaking vacuum and they have not been abused, not a good chance of that fo a 30+ year old carb. Holley makes a nice simple thottle cable bracket that mounts to a corner carb stud and easiliy mounts the GM cable. Check the Jegs online catalog. Brian.
