My 1972 Chrysler New Yorker came from the factory with a 580 cfm Holley carburetor. Transplanted, stock, with only the addition of small tube headers and a 2 1/2" dual exhaust, it couldn't handle it. Had it rebuilt and worked up, still couldn't do it. My friend's 750 cfm Edelbrock nailed it right out of the box, after I set the floats properly. BTW, am now running an 850 cfm Thermoquad, and love it. 18 mpg highway, if I try real hard, and lots of power and rpms on tap. It's just a little too lean, though, and I don't know what to do about that.
