Don't be afraid of Quadrajets!

[TheBMan]

Guys, don't be afraid of Quadrajets. They're great street carbs for a variety of reasons including the small primaries which give excellent throttle response. Mine was setup by one of the masters, Ray Klemm out of Mount Vernon, Ohio, who has done this for me before. If you give him your engine specs, he'll build it so that it works great right out of the box. A knowledgeable builder like Ray is worth every penny. Even if you have a high performance application, a Quadrajet can be a great choice.

Also, the true Godfather of Quadrajets is a guy named Cliff Ruggles. He is also in Mount Vernon, Ohio. He has literally written a book on Quadrajets and is a walking encyclopedia. He trained Ray, in fact. Cliff doesn't do much rebuild work any longer but he sources his own parts and sells them online at his website, https://cliffshighperformance.com/. He has every jet, metering rod, float, gasket, etc and he knows what you need if you tell him your setup and carb number. Noteworthy: his accelerator pumps are made from a material that doesn't breakdown in ethanol based fuel, unlike anything else you buy in the aftermarket.

DO NOT buy parts or "rebuilds" in the aftermarket. Almost all of it is junk.

The only thing I didn't like about Q jets was the soft metal they were made from. 

you usually had to re sleeve everything when you rebuilt them.
