    Rated 5 out of 5 by from Great look and throttle response Bolted up nice on my AMC 360 and fired up on the first start right out of the box. Perfect size for my application

    Rated 5 out of 5 by from This carburetor worked perfectly, right out of the box! Almost no adjustments needed. Very easy to install, and I’m so glad the sales person directed me to purchase this item. My only slight oversight was not buying the air cleaner at the same time. The carburetor kit, is the way to go! Thanks for the help and timely delivery! “I’ll BE BACK”! As they say!

    Rated 5 out of 5 by from Worked Right off the Box Bought this for my 64 Chevelle SS and only needed a minor adjustment. Noticed a quicker take off and smooth idle. Only issue is that it has to warm up otherwise it revs a little to high in the mornings. I may may need to do another adjustment.

    Rated 5 out of 5 by from Finally got the 625 street demon carburetor installed. I only had to adjust the secondary air valve and a minor adjustment to the choke heater. Spark plugs are now a tan color and the engine has crisp throttle response. Great carburetor.

    Rated 5 out of 5 by from I put this on a 72 chevy 3/4 4x4 firewood pu. Where I was using 3/4 tank of fuel I'm now using less than 1/4. I have more power than my edelbrock as well.

    Rated 5 out of 5 by from Awesome features Bought this Street Demon Carb two weeks ago to replace my old Edelbrock 1406. The street demon looked awesome right out of the box. Installed it in my 69 C20 with 5.3 LS1 hot cam. Insulation was easy, it came with everything I needed to hook up to my 4L60 trans, turned the key, fired right up..., This carb made my motor sound and run awesome... I will be purchasing another one for my other trucks... Thank you Holley for making a awesome and affordable carburetor...... #shopjegs..

    Will this replace Rochester qjet without an adapter?

    Asked by: Ichigo229
    An adapter would be necessary for use on a quadrajet style intake.

    I have a 1985 c10 350(quadrajet) th350, what besides the carb do I need to install properly?

    Asked by: Ole2010
    You will need the fuel line and the linkage to connect this.

    Will this carb work on a 1982 van with a 305 350 transmission 

    Asked by: Ricky james
    This carburetor needs a square flange intake, your 82 van probably has a quadrajet intake so you will need this adapter. https://www.jegs.com/i/JEGS-Performance-Products/555/15440/10002/-1

    Does this carb come with all the necessary installation hardware or do I need to get the Demon carb install kit as well

    Asked by: TimmyB
    This is just the carb only. You may want to get the install kit along with it.

    Asked by: Gmack
    I would recommend going a little larger like a Holley 670 Street Avenger #0-83670 or even 700cfm.
