    Edelbrock sells like 8 different versions of the Quadrajet. I see most people talking about the 1904, but there's the 1901, 1902, 1903, 1910, etc.
    Is the only difference the choke? I like the hot coil type choke, but that's unlikely for a Vortec style intake. So an electric choke would probably be best. WHat do you guys think about all the different shades of the new Quadrajets?

    Mike,

    The newest Four Wheeler (March 2002 p. 98) just reviewed the latest Q-Jet.... the #1910.

    It's an 850CFM at WOT, but as you'll see in the photos, the primaries are tiny so it can run a 350, not just a big block. The article really seemed to "gush" about how great it is, how much BETTER than the old Q-Jets it is (even over those custom-calibrated ones that JET sells!)

    The article got me stoked so much that I called Summit the same day the article came out and bought one! [​IMG] #EDL-1910 ($457.95) and the calibration kit #EDL-1992 ($103.39).

    The only "downside" is that this is not a "smog-legal" carb, so depending on what truck you have, or where you live....this might be a big "no-no" for your vehicle.

    I'm very excited to get mine installed, and I'll be sure to share my findings with the group!

    I run the 1901 w/devorced style choke (little stove type that sits on the intake, also called Hot air choke I think). I think this is the best of the 750cfm Q-jets only cuz I have one and it is WAY simple to rebuild and tune. This has been a great carb for the last 7yrs I have been runnin it. Never had any issues with it up until resent, nothing a rebuild couldn't cure[​IMG]!!
    Don't think the choke would work with an EGR type manafold. I run a Non-EGR Edelbrock Performer with this carb.

    I have a 1973 3/4 ton, so I can run just about anything I want to. :)
    I don't have that issue yet - I like the idea of it being 850 cfm just in case I ever need that much flow (not likely.)
    Is the 1910 electric choke?

    Greg,

    I too saw this article..... I was wondering if you knew what makes this "new" Q-jet so much better than the old ones? I run an "old" one on my Blazer, and it will just about run on it's tailgate...!, so I'm trying to figger out if they really made some design improvements.

    Pictures seem to show an electric hookup for the choke....I can confirm when I get mine.

    Marv,

    Article says "completely new and significantly upgraded version of the Q-Jet"

    I'm not sure how far you would get by calling Edelbrock directly.....my guess is that they're not going to make it sound TOO good, or they might be "cannibalize" their own sales of their other model Q-Jets!!!!

    I'm not sure they're willing to make any kind of bold statements yet.....it will be interesting to see if in the long term they phase-out the other models, or re-introduce them with these "mystery improvements"!! [​IMG]

    As a side note, in that same Four Wheeler mag....they showed the Holley Avenger 670CFM carb, which claims to do 45-degree climbs and 30-degree sidehill maneuvers. Not sure if that's considered exceptional or merely "good" to the offroad crowd here....but it's another new carb that's out there now.
