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.





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!





86 Monte Carlo SS - cleaning out the Quadrajet carb and flowmaster exhaust sound
This engine was pulled from the car in 1997 and left sitting in a crate until 2011. They left the fuel in the carb so as it evaporated it left deposits. Exhaust sound at 9:01 3 chamber Flowmasters, long tube headers. 2.25" pipes and I don't think there is a crossover tube.

Quadrajet HP for $40.
A GEARHEAD PRODUCTION. Throw away the Edelbrock and the Holley and save your money. You can build a hp QJ for less, and get better performance and mpg too.





1971 Cutlass SX new intake and carburetor
Just installed my new performer intake,750 cfm edelbrock carburetor,jegs fuel pressure regulator and spectre free flow air cleaner.. Engine makes ridiculous amounts of power and torque fries the tires all the way from first to second and throttle response is very snappy. Thanks to all the help matching up the parts from edelbrock and Scott up at lake Norman speeds.

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.





New quadrajet set up
New air-gap manifold and custom/rebuilt q-jet. Sounds good but I still need to set the timing on the distributor and the carb is tuned already. Hope you like, nothing to fancy just a few revs and walk around...the Exhaust is true dual no x/h pipe and it has cherry bomb glasspacks(3 inch)





Edelbrock Carburetor Installation and Troubleshooting Part 3 - Installation 1
Edelbrock Performer Series and Thunder Series AVS carbs are the most reliable, trouble-free carbs available today, however proper installation and tuning will ensure that you get all the performance you want from your engine. Whether this is your first carb installation or you've been doing it for years, this video shows you how to install the carb on a variety of intake manifolds, how to check linkage and vacuum line hook-ups, set the idle speed and mixture, and help you diagnose any potential trouble spots. In some cases, additional tuning will be required to calibrate the carburetor for your unique requirements, and this video shows in detail just how easy it is to get the carb perfectly "dialed-in" for your combination. http://performanceparts.com/ http://www.edelbrock.com/automotive_new/misc/tech_center/install/tech_vids. shtml http://performanceparts.com/vendors.php?vendor=ELB

OLDSMOBILE 455 W-43 EXPERIMENTAL HEMI AND OTHER EXOTIC ENGINES - THE JOHN BELTZ YEARS PHOTO TRIBUTE
John Beltz was Oldsmobile's chief engineer in 1964 and one of the prime movers of the Toronado and 442 project. Beltz was promoted to Oldsmobile general manager at age 43 in 1969 when Harold N. Metzel retired. Beltz passed away in May of 1972 from cancer at the age of 46. John Beltz is leaning on a dual fan 455 Olds and posing with other experimental Olds engines that never saw production. Here are descriptions of these engines: 1. The 0W-43 all aluminum 455 with 4 valve per cylinders, four overhead cam Weber engine. With a redline of just under 8,500rpm it was originally conceived for CAN AM racing. At 3,000rpm it put out 300hp and at 6,000rpm registered over 600hp. The top output recorded for this engine in the Lansing Dyno facility was 700 real hp at 6,800rpm. Tests were run with both carbueration and fuel injection. The block was cast from Reynolds 356 alloy and fitted with pressed-in dry steel cylinder liners for the Forged-True 12.20to 1 pistons. Billet steel connecting rods by Carillo was used along with a forged steel crank. The engine weighed in at 50 pounds lighter than the production 455 motor! It was developed at the same time as the ZL-1 Chevy 427 motor. 2. The W-43 4 valve per cylinder 455 developed by JOHN BELTZ , LLOYD GILL , JOE JONES AND FRANK BALL. Rated at 500-550hp with a single Rochester Quadrajet on an aluminum manifold. Constructed with both cast iron heads and block and with aluminum-alloy block and heads 75 pounds lighter than the conventional 455 production engine. Engine featured four valves per cylinder with narrowed angles for a super efficient combustion chamber design, central spark plugs and could easily be adapted for chain for gear driven overhead camshafts. 455 engine had 4.625inch cylinder centers, a 4.125 bore and 4.250 stroke. Making use of the 3inch main bearings and 2.50 inch rod journals, the engine was fitted with a specially prepared cast crank fitted with SAE-1140 forged steel rods, forged 10.20-to-1 pistons which rode on Morraine 400 bearings. Four bolt main block boasted 2 additional 5/8inch drain holes. Four valve heads featured 1.750inch intake valves (SAE-8640 steel) with 22 degree stems and 1.375 Exhaust (214-N stainless steel) with 15 degree stems, special Stellite seats, bronze alloy guides, o ring plug tubes, 14mm spark plugs, 3/8 inch pushrods and aluminum rocker arms. (Of all the experimental Olds engines, this one came the closest to production and there are photos of this engine in street gear. MAY 71 HOT ROD MAGAZINE features some of these engines and the sadness of the Olds engineers of that time of how they would never be released.) 3. 455 dual turbocharged CAN AM ROCKET CHALLENGE. 659hp @ 6250rpm. 554lbs torque @ 6,250 rpm. Alloy block with 4 bolt mains. Forged steel crankshaft. Forged True pistons with 8.5 to 1 compression. 3inch main journals. 2.499inch rod journals. Carillo billet steel rods. alloy heads. 2inch intake valves. 1.625inch Exhaust valves. Crower roller camshaft with 555inch lift and 320 degrees duration. Dual TRW-375-E-10 turbochargers with Boost Wastegate 10and 1/2psi. Lucas fuel injection. Olds alloy intake. Competed with big block Chevy Mclarens and Porsche Panzers in CAN AM racing circa 68-69. This video is merely a couple of old magazine pages strung together with the exception of that blue 455 hemi which was found on the internet. Thats BRUCE MCLAREN in that green can am race car which is Olds powered. AT THE BEGINNING OF THE VIDEO JOHN BELTZ IS POSING WITH SOME ENGINES FEATURED IN THE JULY 1969 ISSUE OF HOT ROD MAGAZINE AND THE BLUE OLDSMOBILE 455 HEMI WAS FEATURED IN THE MAY 1971 ISSUE OF HOT ROD MAGAZINE. The incidental music I overlayed onto this video was muted by youtube.





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.
