I have an 86 K5 that originally had a 305 with a quadrajet. It now has an 85 350 crate motor with an edelbrock 600. When the new motor was put in all the emissions equipment was removed (I was young and stupid) so it is just a straight forward motor with the only wires running to the carb being those for the electric choke. What style/ year quadrajet would be the best for me to run? If I got one for an 85 could I use it and just not plug in the mixture control wires and whatever else there is, or do I need an older one made for an engine without all the emissions parts? Help! hills dont like my edelbrock carb very much and I need them to before memorial day weekend.
