Well that Buick is pretty heavy but I have always heard mostly good things about the quadrajet. I took one off my 1976 Corvette 350 and replaced it with an Edelbrock 600CFM four barrel on an Edelbrock Performer RPM and most of the time I get 16 mpg but on highway driving I have gotten 17 mpg but my roadster is only 2800 pounds with me in it and the rear is an 8" Ford with 3.55 gears and the trans is a 700R4 with a 4th gear OD. Actually this was disappointint to me but it is almost exactly what the 1977 Z28 got with a four speed in the 1977 reviews.
