Edelbrock Q-jet
« on: May 10, 2025, 06:02:40 PM »
Reading Cliff's book, it has a section there about the Edelebrock Q-jets. Most of the discussion there is about the RPM Q-jet, with a recipe and other features of this high performance unit. I know there were other replacement carbs available from Edelbrock, but there is little info on those replacement units. Are those desirable and good candidates for a hotrod with proper rebuilding and modifications? I am guessing Cliff's parts would work on those?
Thanks for any replies.

I have a 1901 unit I used to run on my 350. Couldn't ever get it to idle worth a damn but ran good at higher throttle angles and wide open. Turned out to have a worn throttle shaft bore... brand new. So I shelved it for the rebuilt stock one I use now. I think if I was to use bushings to fix the vacuum leak at the shaft it would be a great carb, but that is currently lower on my list of things.

Edelbrock produced three different models.  The first two 1901/1902 are divorced choke, 1903-1910 are either hot-air or electric choke. 

All are very well made carburetors.  My favorites are the later hot-air or electric choke units as they are more universal and bigger cfm.

I sell parts, rebuild kits and custom rebuild kits for all of them based on what the  owner is going to do with it.......

Hello all-

Newbie here but my 1st dip into the Qjet world was a 1910 purchased from that guy Merrick Motors in CO on top of a fresh 455 with Edelbrock mechanical pump-and nothing else (no regulator).  Kept flooding out the top couldn't get it to run for more than a few minutes.  Junked it for a Holley that bogged like crazy.

Got $450 for the 1910 on ebay- took the cash got smar and bought a custom Qjet +dizzy from Cliff.  Still in use this day, on the 2nd motor since then and it runs flawless.

Moral of the story, I spent just hair more building a factory Qjet that runs perfectly than buying the 1910 and having to dink with it..  They seem OK if you happen to have one, but IMHO not worth seeking out VS a desirable factory unit.

JMHO

IT's hit and miss for sure with the Edelbrock 1910's.  I've seen quite a few problems with them over the years.  Machining errors, different calibrations and for sure in most cases they are going to need some help before you put one in service....
