quadrajet

I just finished a frame off restoration on a 67 firebird 400, the car didn't have its original carb, the previous owner had swapped it out for a quadrate from a 1978 trans am which also have a 400 ci engine. Anyhow, I get a raw gas smell at idle and wondering what the problem might be. couple...

I have a mildly built 468, w/long tube headers running a heavier cam & a q-jet carb. When I really stick it on the road, it will kind of bog down on me and pop-pop-pop-pop. (Its also open headers since its too low to run proper exhaust on right now) I reckon it's my fuel pump that's the problem...

Looking for advice on a manual fuel pump with a PSI low enough for the quadrajet. Previously had a AC DELCO 40727, 7.5-9psi was far too high for the QJet. Input? *Relevant info Truck: 1969 K10 (Manual) Engine: 1977 (Mark IV) 454 Carburetor: 1973 R4-4MV Rochester Quadrajet

Hey everyone, I'm having trouble tuning this CCC carbureted 305 Monte Carlo. I rebuilt the carburetor because it had leaky gaskets, but ever since I've rebuilt it it runs insanely rich. I reset all the carburetor parameters to as close to stock as I can but it doesnt help. I ended up with the...

Hey everyone! I'm having trouble with a quadrajunk equipped 85' C30 454 that I'm trying to get operational for a buddy. I've never tackled a quadrajet before, but I've been through quite a few Holleys and figured I'd give it a shot. I'm slowly regretting this haha. Here's the deal, neighbor...

I need a new carb for my Camaro. It's a built 350 with Vortec Heads and a LT4 Hot Cam. The motor should be around 400hp. Should I go with a QJET or a Holley? My dad said both work well and its my choice. Its a 5 speed and its a weekend fun car. I want good throttle response and decent gas...

Just a heads up - drove cross country (Seattle to Rhode Island) and finally did an accurate mileage test with gps and full tank of gas + refill. After about 300 miles, i refilled and to my surprise she got 21.7mpg highway, fully loaded with car parts, snowboard gear, camping equipment for 2 ppl...

May 23, 2015 Just signed up. I am putting in a new cam in my '83 Olds Cutlass Supreme. I got it running, kinda .............. Have an electric Quad carb., and can't keep it running. Seems like it's runnin' outta gas??? Been doin' this stuff for over 60 years but first time using this...

I have a 1972 pontiac grand prix with a 400 ci engine & rochester Q jet. I am experiencing very high idle at 1500 and can't get it to come down any lower. I have checked all vacuum lines and the carborator base gasket. I did a check with liquid at intake mani bolts without finding any leaks...

Hi. I'm having some trouble with the quadrajet on my 77 camaro. It won't run clean, and when i try revving it goes even rougher and slowly builds up revs. I'v had this problem since about 2 months after i installed the carb along with a new intake (edelbrock torker II). The weird thing is that...

I just restarted my sbc 350 with a rebuilt quadrajet. I have 74 jets, and 46 primary rods. Before the carb rebuild, it ran fine. I damaged one of the origianl rods, so had to order two new idlebrock aftermarket rods (1946). Its a 75 era' MV quadrajet. It it now idling high, and have jets...

Hi All, I have a 1977 Chevy truck with a stock crate 350 engine and a 3-speed auto transmission. It seems to be suffering from power loss when in Drive. I drove the truck yesterday to move for the street sweeper and it gave no trouble. This morning, the truck started up just fine, but when...

**If anything is mislabeled or the information is incorrect, please let me know! Thanks! - Background - I have a '77 Chevy pickup that became victim to water and debris in the gas tank (you can read up on that story here.) At this point, due to the debris getting in the carburetor, it has...

Hi All, First off, hope you all had a very merry Christmas and are enjoying the holidays! My question is regarding a '77 Chevy. I will admit upfront that I know nothing about carb'd vehicles. Now, for the story... --------------------------- This past week... My '77 truck recently began...
