See 1976 Chevrolet pickup with Rochester quadrajet upgrade on SBC 350 V8. We removed the hood, mounted a camera looking down on the air horn, and took it for a spin, running wide open on an uphill grade. See how the secondary air valve responds to rpm drop at each upshift of the THM. Also included is a smoking burnout.

More Quadrajet tuning, some things! Part one in this saga on Sept 13, 2010
The car has a slight stumble and surge at a light throttle cruise at about 55 to 60 MPH. By swapping out the .050 metering rods to .048 units, the stumble and driveability concerns are now gone. Going richer would mean worse fuel mileage one may think? No! Now that the mixture is right, LESS throttle opening is needed now, which means higher vacuum, and this way the metering rods will block off the correct amount of fuel, and in the proper timing and percentages, so the car runs much smoother. As stated many times, patience and reading up on, and understanding how these intricate carburetors work will help out very much! Enjoy!

A 79 chevy C-30 dually pickup w/ 454 V8
Here is a friend of ours chevy pickup. I've been told it's a 79. It has a 454 big block V8, a turbo 400 3 speed direct automatic, and dual Exhaust which i don't know who makes the mufflers. We changed the carburetor to a edelbrock 4 barrel in place of the quadrapuke (quadrajet) carburetor. Quadrajets are good carbs but when they go bad, they're bad. The quadrajet on this was really bad, the throttle bushings were worn on it and it when the secondaries opens up i'm assuming it just dumps fuel like crazy because when we floored the gas it was like pop pop braaaaaap. With the old carb on it used a quarter tank of gas to drive 10 or 15 miles.





How to identify 4 barrel carburetors
Here's a guide to help identify the most common 4bbl carbs including Edelbrock, Quadrajet, Holley and Thermoquad. There are a few older or more obsolete carbs not shown including Rochester 4G, Autolite-Motorcraft 4100/4300/4350 and Carter WCFB that I'll detail in the future provided I can actually find one.

how to minimize engine bog with a Quadrajet carb
this is to minimize engine bog when the pedal is to the metal. do not over tighten, very small spring...you want to try 1/4 turns or 1/2...q-jets are good if tuned properly. also when you are tightening screw it will have tension on it so keep the screwdriver firm. 1986 gmc sierra single straightpipe to cherrybomb. you will need a small flathead screwdriver and a 3/32 allen key. be sure not to tighten to much or else your vacuum secondary flaps wont open.
