I was just sent some photos of my 7028271 XP Quadrajet that was just plated back to factory finish. Boy-oh-boy does it look nice. Now it is in route to Cliff High Performance for the his final touches.
This was the correct numbered carburetor for my 400 HO 4sp. You will notice the date code of 2137 which translates to Aug 1, 1967 which is the perfect date for my Sept built bird.
