The season is over, and my carb is in need of work. Since I am going to have it off, and all apart, what should or can I do to it to make it perform better? preferably without drilling or modifying it.

A good starting point would be to pick up a copy of the book by Doug Roe called "Rochester Carburetors". It explains a lot of the more popular tuning and performance mods needed to help out the quadrajet.
To list and explain all the modifications and tuning tips here would take a book.

Hope that helps, and if we can help with specific symptoms your carb has, just ask.

Even if you dont modify your carb that book is a GREAT addition to any toolbox if your running a q-jet. It does a great job of explaining how everything works.

i bought one from jet performance for like $400 and it wasn't worth throwing the the track can. I had the local speed shop from where i am from Competition Automotive in Shreveport, LA build me one for $175 and that is the baddest Q-Jet i have ever seen. i now have a street stock and we run it on that now when we can run alchol and a holly double pumper. just my 2 cents. here is his number. 318-635-8108.

Or.....when everyone gets tired of fooling with temperamental quads, we're here to help as well. From mild to absolutely wild, there isn't a quadrajet we can't improve noticeably.

Always willing to assist all racers....
