Holley 625 cfm street demon
Anyone using one of the carbs and if so how do you like it? I am considering ordering it for my 77 cutlass 350.

They are a good design, heavily based off the Carter Thermoquad with a bunch of improvements with new 3 barrel castings and that is a great sale price. You will need a tuning kit, a member mentioned they are calibrated for 9+ to 1 motors with a mild cam.
