1974 225 Emissions questions
I just installed a real nice running 74 225 into a 73 Dart Swinger. While the engine was out, I removed the emissions system for painting and new gaskets. Now I'm wondering if I should reinstall these components or leave them off. They include a resistor block that the electric choke connects to, a vacuum amplifier, another vacuum/electric relay of some sort as well as multiple vacuum lines and a couple of plug in boxes, one on the firewall and one on the DS fender well. It also has an EGR valve in the exhaust. Will it run better or worse if they are left off? or should I just reinstall everything and keep it original. I'm assuming the 73 system was different as there was a small vacuum "box" on the firewall where one of the electrical ones is on the 74. I believe vacuum went through this box before it went to the distributor. The 74 does not have vacuum advance on the distributor. Do those little boxes somehow control the timing? If I leave this stuff off, should I remove the EGR and block it off with a plate? What have others done?
