Rebuilt Rochester 7043251 Quadrajet Carburetor Oldsmobile 455 442 cutlass 750cfm for Sale

Price: $192.5

Rebuilt Rochester 7043251 Quadrajet Carburetor Oldsmobile 455 442 cutlass You are bidding on a professionally rebuilt and tested used Rochester Quadrajet. I removed this carburetor from a 1973 442 Hurst Oldsmobile with a 455 v8. This is the large 750 CFM big block model. The # is 7043251 RB Date code is 1663 The carburetor ran fine but I sent it out to a professional QJ specialist builder for my 1970 442. I ran it for about 20 miles and it runs and idles perfect. I recently found the correct date code one for mine so will not need this one. This carb will fit any GM and especially Oldsmobile small or big block. Clearing out extra stuff so they are being sold. No Reserve!!

Hi guys,

I will go ahead and let you know that this is my first Carburated engine, I have always run Fuel Injection. With that being said I am a little out of my relm. Any way this might open up a can of worms but I have a 455 big block, bored .30, Edelbrock heads with minor port work, performer intake with minor port work, 242/572 custom grind cam, headers, magnaflow exhaust, 10:1 compression.
I am looking to purchase a new carb, the car currently has been driven 31 miles with a 750 quadrajet and its really losing power above 2800 RPM. Timing is correct, plenty of fuel pressure. line size is fine, plenty of vacuum, etc etc.
I am debating a Ultra Street Avenger 770 V.S. carb or a Quick Fuel SS 780 V.S. I am also running an Art Carr 200R4 with a 3:23 posi rear. The car weighs 3500 lb with driver and fluids. What would you suggest?

Thanks

I have a Holley 750 on my Olds motor. If you plan on doing events with it, then step up to road race floats.

I would think an 850 with annular boosters would be more appropriate if your turning it over 5,500. If you have the extra $, I would recommend a carb builder instead of an "out of the box" or at least a wideband to help tune it.

Pro Systems was the same price as a good out of the box Holley. Tell them what ya got, and what you do and Patrick will have a carb built for ya.

Those big block Olds engines arent to RPM friendly, 5500 would be the MAX

Nope the olds motors are not known for turning high rpms. But the 850 annular discharge would work great on that motor. The annular discharge booster creates a better fuel atomization out of the booster than the standard down or dog leg booster. The annular will make more power throughout the entire rpm band than the other style booster. The annular discharge booster is also easier to tune and has better driveabilty. The only issue is you cant get an annual discharge booster in a vaccine secondary carb or at least not that I know of.

That all depends on the big block Olds... Note my signature.

I still say an 850 with annulars is the way to go, double pumper might take a little more time/ effort to get right but will almost always out pull vacuum secondaries. If I had the $ I would send my carb out to a builder though, someone above emntioned a good one but there are lots out there. Heck we have what I consider to be an awesome carb builder right here on the forum, Shaker455 what do you think?

my best guess from the info you posted would be an 800 or 830 cfm, holley would my preference. i doubt you'll need anymore than that.

Keith,
I GREATLY appreciate the help. Just keep in mind this car will never see the drag strip, its life will be mostly the power tour, lots of stop and go traffic cruise ins etc, I do want power, but I mainly want drivability. Most of the cars I have been in with a double pumper ran awesome but loaded up in traffic, but let me say this I AM A CARB IDIOT. thats why i am here asking for advice, and your advice is very important to me!

I'm not clear on your cam specs but an off the shelf choke towered annular 850 would work fine on your combo and still have some nice bang when you want it.

How To Quadrajet Carburetor Rebuild - Part 3 - Tuning

what size carb for a mildly built 455

Nice build platform. From what I've experienced, bigger isn't always better. The total cylinder/head "area" is normally considered when solving for CFM volume. So that puts you in the 650-750 range by charts the manufactures offer. Not exactly an absolute size here. Porting, headers and intakes make more efficient flow but not really considered with CFM sizing. The tricky part is valve size, lift, and duration. If factored, this can add to the optimum CFM required. So, solving for the exact carb on an unknown engine is a bugger. If you purchase something undersized, a Craigslist ad fixes that. An oversized carb can be a fire hose that also goes to ad. Your best bet is find similar builds and document what they ended up with. Guess and experiment.

For a reasonably priced starter (hopefully keeper), Quickfuel has both a 680 and 780 in their Hot Rod series. Great $400 carbs. Basically a well tweaked Holley.

If you're looking for an out of the box carb that will work great often without any tuning required, check out Edelbrock Performers 650-750. * Use them and would recommend to friends.

I think anything over 780 might be pushing it without forced air? Really surprised about the big numbers reported. Maybe these bad boys can run dandy fine with lots-O-fuel? Hoo hoo.
