750 vs. 800cfm Rochester Quadrajets-how to tell them apart
There exists a ton of misinformation regarding the actual airflow capacity
of the Rochester Quadrajet. Not many people know how many variations there
are or how to tell them apart.
Here is a simple video explaining how to identify each size based on
casting design. I will cover the "cfm-limited" carbs in a separate video.
How to identify 4 barrel carburetors
Here's a guide to help identify the most common 4bbl carbs including
Edelbrock, Quadrajet, Holley and Thermoquad.
There are a few older or more obsolete carbs not shown including Rochester
4G, Autolite-Motorcraft 4100/4300/4350 and Carter WCFB that I'll detail in
the future provided I can actually find one.
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.
Looking under the hood of the Jimmy for the first time. Assuming the tag
has been painted over or rubbed off this is a how to!. thanks for watching!

This is a video for a ORIGINAL 1963 1/2 Galaxie 500 XL "R" Code
convertible. This just received a complete full rotisserie restoration.

only about 10 of these still known to exist as of today. This is by far the
best of the 10 or so that remain! If you are interested please feel free to
call me directly at 570-875-7109.
Please note that this is not a cheap car. 3 of the 10 have sold in the past

not all correct drivetrain to a car just like this one all correct and a #1
condition which sold for $192,000. This car is in the lower range as for
price but is a TRUE #1 condition CORRECT car. The owner wants to really
sell the car this is why The car is priced at $119,950. Again please feel
free to call me at 570-875-7109. Thanks, Marty
