Question for the Quadrajet gurus on here. I was running the numbers from the Quadrajet on my '72 GMC and came up with something interesting. 7040511. As far as I can decipher, this carb was made in 1970 and is a California emissions carb. What is the difference between it and a regular Quadrajet? Can I rebuild it back to regular specs or should I look for a different core?
And no, I'm not interested in putting a Holley or Edelbrock carb on it!
