    Question Carburetor Size??

     



    I have a 383 stroker, aluminum heads 64cc, aluminum roller rockers, 557 cam ( not sure of duration) Looking for a good 750 carb for it. Thanks

    A 750 seems a bit large for that motor. 550-600 is probably good for a street/strip setup.

    It'll make the most power with a 750. Driveability (throttle response) may be a little better with smaller primary venturis.

    If you haven't yet purchased a manifold, I'd recommend a Performer RPM spread bore and a 750 Q-jet. You'll be very pleased with the results. GM used this carb on 305 - 350 engines and it just flat performs. There's nothing like to sound of those monster secondaries coming to life!

    Ken,

    My stroker sounds similar to yours and I run the 770 Street Demon on mine. It was dyno'd with that carb and set-up at 457hp. I run the Preformer Air Gap manifold with a 1" spacer. My cam is a .248 duration int/exh with a 613 lift as I recall. As folks have commented, so much comes into play on choice of a carb. What trans do you run? I run a shift kitted 700R4 with 2800 stall. I am totally happy with how mines runs out...
    My 2 cents worth - Greg

    I realize I am posting to a carb thread/crowd and should likely find a rock to hide under after this entry.It is off topic sort of too.Well it is a fuel system.I suggest this O/P looks at Edelbrock EFI fuel injection systems which is tune on the fly and has systems that are large enough to support the size of his engine.The newer versions are SFI,but pricey.

    Yes, and did you see the new deal by FAST? They now have a setup for dual "quads".

    All deppends on cubic inches and how many Rpms it will turn.
    I think Bluvelle is probably closer to the carb size.
    750 is to small for my built 351 Cleveland.
    Really depends on how hard he's gonna run it.
    Also thats a great choise on a intake to Bluvelle.

    Yepper-I saw that.Thing is Fast seems to have a lower entry level cost,but to buy all the parts to complete it costs tons more.

    I've never even considered any of these systems actually! But with a recent purchase of an intake that may have changed. I have heard some good things of the FAST System and it's products. But, as always - cost will be a factor!

    Thanks Kurt!
    I'm very happy with the way my car runs out and I think that crab/manifold match-up is optimum for my lil' stroker!

    I have a 383 that was dyno'd at 450 hp/468 ft lbs of torque. I run an Edelbrock 750. I know I probably could have made few more hp with a Holley, but I like the Edelbrock because I can get 20 mpg with it out on the highway. Any of the carbs mentioned will work well for you. It essentially boils down to a matter of personal preference.

    best for cost effective is the above mentioned qjet. "750" qjets have flow tested near and above 800cfm with the spread bore you get awesome throttle response for the street and good milage (as long as you keep your foot out of it )as far as intake edelbrock victor jr. air gap is almost fool proof to make power with

    edit: qjet can also be reworked to flow over 1000 cfm so it can grow with you

    Since you live in Illinois like I do, I would recommend the Performer RPM intake rather than the Air Gap if you plan to drive it is cool or cold weather. Air Gap intakes do not like cold weather. If it is a fair weather car, then it won't matter.
