I have a 1985 gmc c1500 305 h motor canadan made with all the garbage on it smogg pump etc. My state does have inspections ect. I bought a carb. 500cfm and a new intake manifold, and a regular distrubator hei, my question is can you tell me everything I can get ridd of so when I add the new stuff it will run better, my truck isnt computerized eather. Also should I get rid of the tip in tip out switch on the firewall? Some say yes some say no I dont even know whats it for thank you.
