I have a Quadrajet M4ME, #17084226 with original intake manifold on the 305 I'm rebuilding. This is going in my 56 Chevy Truck. Should I change to the 2101 Intake? Will this Quadrajet work ok without the EGR and ither smog stuff or should I find another carb as well? Or should I just stick with what I have? My first inclination -- wallet you know!
