i have a quadrajet carb on a olds 455 motor and was going to put a edelbrock
750 carb on it, the oldtimers that i talk to say keep the quadrajet and the
younger guys say go with the edelbrock.. what is the pros and cons of each?
i hear the quadrajet will get way better gas mileage. the motor is in a 58
buick special with no internal mods done to the motor. the only thing i will
be changing is to a edelbrock performer intake. any help is appreciated on
this matter |

The Edelbrock designed for that application will be a spreadbore anyway!
Stay with the Quadrajet!
It's more tunable, if you find the propper sources, you can get the metering
rods to tune it, I have yet to see anywhere that sold any Edelbrock tuning
parts?
The manifold would be a definate improvement, but if the Edelbrock was
designed internally after the original Rochester Quadrajet theoretically,
why change what they imitated?
A well adjusted Quadrajet is less likely to go out of adjustment, less
likely to fail with tiny rust particles. Every Edelbrock that was flooding
that was brought into my shop, had ever so slight an amount of rust on the
bottom. Any Quadrajet that failed, had to be a quarter of the way filled
with rust before it failed.
There's some edification, on which to base your decision on. If you're going
to switch, go Holley. The folklore that you always have to readjust them in
the group means: An idiot forgot to put the leather rins around the idle
adjustment screws and tuck then into the metering block!
I hope this helps?

Good Luck!

I agree, if your going aftermarket, buy a standard flange manifold, and a
Holley 600 cfm for milage, or a 750 for power. I also agree, a well set up
Q jet is a great carb. I never had any luck with them, and went to a
Rochester 2GC by using a two to four barrel adapter mounted upside down,
allowing the two barrel to feed the four barrel manifold. This is a killer
setup for stop and go traffic. [ most of my driving ]
You can't beat the stock manifold for reliability. >> Stay informed about: quadrajet verse edelbrock carb |

Go to my sbc engine webpage and there are about 5 links to rebuilding,
tuning, identifying, metering, andn optimizing your quadrajet.

The advice on using a Holley is good. Both Edelbrock and Quadrajet
can do a decent job at metering fuel when properly tuned. So can the
Holley, of course.
But here is the rub: Only the Holley has a widely adjustable
accelerator pump that can provide a large and correctly-metered squirt
of fuel for instantaneous and powerful throttle response. Yes, the
accelerator pumps in E or Q brand carbs are adjustable, but they
aren't as large as a Holley.
Your 455 will want the large accelerator pump for good throttle
response.<!-- ~MESSAGE_AFTER~ --> >> Stay informed about: quadrajet verse edelbrock carb |

If this post stays here long enough you will get advice on everything from
old Stromberg 94s to the latest in EFI computerized systems. No matter what
brand carb you talk about someone has no use for it and others just love
them. You're doing the right thing in getting opinions.
Just a thought is you are going to use an Edelbrock Performer manifold.
Unless it is the exact Olds replacement then it has a square bore carb
mounting surface so that excludes the Q-Jet ( unless you get an adapter )
and leaves you with either a Holley or an Edelbrock or one of their clones.
Either of these type carbs is a good choice when in the hands of the person
who knows what they are doing and installs and tunes them correctly.

I also need opinions on a Quadrajet and a corresponding dual plane intake.
My specific issue is getting my Quadrajet rebuilt including the Throttle
Body Shaft Bushings by someone reputable close to Ohio.

Most of the major remanufacturers don't even do that any more!
You might have to boy a junker for the base plate.
Sorry for the bad news, but it the base plate is worn, the shaft is worn
also.
I hope this helps?

There is a shaft drill and bushing kit out there somewhere
I know I've used them before and still have it.

Thanks for telling me!
I'll look for it, but if the shaft is shot, I'll still have to look for
another carbureator.
Thanks,

If it's the Performer, then it has the quadrajet spreadbore mounting.
If it's the Performer RPM then it has the square bore.

Do they still make the Predator? Now *that* was a carburator! Highly
tuneable, reliable, easy to keep clean, & no float/needle/seat to cause
flooding.

Why waist good money on buying a replacement Quadrajet or carburetor. A replacement Qjet will have the same trouble down the road anyway. The biggest trouble with the Qjet are the throttle shaft bushings and the warping of the air horn and fuel float bowl assemblies. Warping happens when the two front mounting bolts are over tightened. Because of the thick gasket between the fuel float bowl and throttle plate it allows for the bolts to just keep tightening and this is the main reason for the warping. This causes internal vacuum leaks, fuel to leak and poor performance. You can see this warpage by placing a straight edge over the 2 front bolt holes to the matting surfaces. If you can see daylight you got warpage. If the engine wont idle more than likely the throttle shaft has vacuum leakage. Addressing these issues and you'll have what we think is the best carburetor made to date.
