It looks like the Quadra-Jet is the carb of choice for my setup. Do I understand that Edelbrock makes a Q-Jet clone for my pre emissions era engine? Should I also be looking at a different manifold or is the stock one OK? This truck will be a daily driver and I am interested in reasonable performance as well as decent fuel economy. Don't want a godzilla machine but one my wife can drive so dependability is also a requirement. Thanks Weeds
