hinz57,
I would recommend the #1406. I have one on my 305. Emmissions is based on where you live. If you don't have any emmission testing I would get rid of all the equiptment. The carbs look very nice. See my installation

If you have a stock intake you will need a spacer/adapting plate. I would recommend a four swirl hole 1 inch adapting plate. The four hole swirl adaptor will help increase low end torque. You will also need an EGR valve extendor. The factory EGR valve is too close to the carb. The square bore carb will not bolt up unless you move the EGR valve with an adaptor. What type of transmission are you using? The TV cable for a 700R4/350TH will not align up properly. You can use the factory bracket but I recommend a new bracket to properly align the throttle cable and the TV cable. Since you want to change the carb why not change the intake too. The Edelbrock dual planes start at about $119.00 for an emmissions type.
