Report 1982 Carburetor in 1965-83 Avanti Posted February 17 My own recommendations...not necessarily the best...is that while the Quadrajet is an outstanding carburetor...there are no new ones being built. All are very old by now and rebuilt who knows how many times by now...or abused and in disrepair if not having been rebuilt. It takes a good rebuilder who understands the Q-jet to rebuild one and set it up properly...talents in short supply these days. Do not...I repeat...do not buy an assembly line rebuilt carburetor. They will only cause trouble as they're not set up for any car in particular...plus they're just as likely provided only a cleaning and some new gaskets, floats and bushings replaced. I would suggest (as already stated) to get a new Edelbrock Performer (1403) or Performer (9903)...along with a Performer or Performer EPS intake manifold. The standard Performer intake can take either a spread-bore (Quadrajet and some Holleys) or a square-bore carb (Edelbrock). The Performer EPS is optimized strictly for the Edelbrock square-bore carbs and posts somewhat better horsepower and torque numbers....but it sits slightly higher so clearance may be an issue. There are good oe-type or performance distributors on the market. Most any should work admirably. I also agree with getting a true dual exhaust...but first check and make sure the frame has the openings on both sides of the X-member for pipes to pass through. After a certain point some Avantis were only given one clearance hole for the exhaust. If you can run duals...or even only one...get the biggest diameter pipes that will fit without hitting the frame. Let that engine breathe! I know this might run more than you might want to spend. I'm just saying give it some thought about what you want out of the car and then assemble the parts that will accomplish that. You can always call the tech line at Summit Racing...they will ask you questions and give you solid advice regardless of brands. You can call Edelbrock for their advice and get probably the same answers but they'll recommend their products of course. Edelbrock makes great products but they're not the only good name out there.
