Hello, I'll post an introduction to the forum soon, but I just picked up a 1973 Numbers Matching Formula 400 w/ ram air. Car runs and drives very smooth...but I have some red flags when it comes to the Quadrajet Model that is installed. Also the carb linkages and secondary plate operation is pretty gummed up. I wonder if the secondaries are even working properly under load.
Carb on there is a Rochester Quadrajet 7040247. This number indicates it was for a 1970 Buick with a Manual Trans. Does anyone have any feedback about this model of Carb as it relates to a 1973 Ram Air 400? I've worked on vintage motorcycles for years, but this is my first adventure into cars.
Here's a quick video of the carb itself and the condition. The EGR is not connected and the Valve cover breather is just floating around not connected to anything. I'm going to be going through to understand all the vacuum lines to see what isn't set up properly. But I figured I'll start with the carb.
Thanks for the feedback and any other info I can provide I will.
