Here is a link to an articles about tuning the Quadra-jet;

The folks on the Corvette Forum consider Lars to be the guru as it pertains to Quadrajets and once I get a few things sorted out on my 76 Corvette I am going to send him my QJet for a rebuild.

I really just need to know if there is a difference in quad for 69 to 79 because 79 had a lot of pollution and I was wondering if the 79 carb. due to that fact would reduce power

I don't believe so. The electronic controlled carbs were sometime around 82 IIRC and if I'm wrong someone will correct me. The one thing I'd do is to run an electric choke. I believe this is the one I'm using on my 76 Corvette. https://www.ebay.com/itm/Rochester-E...kAAOSwkvtb43DZ
