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.

69 GTO Judge Drag Car Pictures & Video
This is the GTO I built and raced between 1984 and 1992. Anyone know where it is? I sold it to a guy in Memphis TN when it got to the point that you couldn't be competitive without a trans break and delay box. The picture of the baby blue 68 Tempest is how it was when I bought it from a guy named Lowel in central FL. The Dorn Brothers in Sanford did the body work and awesome Orbit Orange paint. Ken Wells built the TH400. I built the engine and rear end etc. The car weighed 3500 lbs with driver. Best ET/Speed: 1/4 mile 10.36/132mph, 1/8 mile (set up for the 1/4) 6.55/103mph, 1.48 sec. 60 foot. This is the first and only Pontiac I ever built. It was a stock bore and stroke 455 with cast rods and crank. "62" D-port heads, measured 11.2:1 compression ratio using TRW forged flat top pistions. Torquer intake, 850 Holley. Crower mechanical cam. TCI 5000 stall 8" converter. 9" Ford with 4.10 gears, Strange spool and axels. Shifts were at 5500 rpms and it went through the 1/4 mile traps at 6200 rpms. The rear tires were 14 x 33 MT (I hated the MT's, Firestones and Goodyears hooked better). I fabricated the headers from a Headman Hustler (flat collector) kit and they were worth .2 sec off the ET. The first time out, I had $5000 in the car and ran in the 10's off the trailer with a Quadrajet. By the time I sold it, I had better than twice the money in it and had tuned 6/10th off the ET. I raced it all over FL, GA and TN and had only good times with great friends. Like they say, a bad day at the track is better than a good day at work. Hopefully I'll find some of the in car videos from Memphis where it carried the front tires 3" in the air, 6 feet out, remember, this was old school, foot breaking it.





How to adjust Quadrajet/Dualjet fast idle
Quadrajet/Dualjet Rochesters have a fast idle adjustment screw that is separate from the base idle screw.Here's how to locate it. NOTE THAT THE CHOKE ITSELF MUST BE WORKING IN ORDER FOR THE FAST IDLE TO FUNCTION.

How to de-bog your Quadrajet part 1
Sorry guys, I got the videos a bit out of order. The Rochester Quadrajet has gotten a bad rap over the years, often called a Quadrabog or Quadrajunk. In fact, this is a great multipurpose carbureter once you understand how they work and what not to do to them. In this clip I introduce you to the Quadrajet and begin explaining the theory of operation of these units. Enjoy!

How to de-bog your Quadrajet part 2
The Rochester Quadrajet has gotten a bad rap over the years, but it's actually an excellent carburetor once you understand how they work. Often referred to as "Quadrabog" or "Quadrajunk", many of the issues these units suffer stem from neglect, or "modifications" that do more harm than good. Being a spreadbore, air-valve secondary design, the Quadrajet is capable of flowing 750 or 800 cfm of airflow, eliminating the need to buy different carburetors when your set-up changes. In addition, the small primaries make for great drivability and fuel economy. In this clip, I'll discuss theory of operation on the secondary side, since that's where most problems arise. So, leave your preconceived notions at the door and let's see what makes these carburetors tick.
