Question about 1984 Chevrolet Chevy

1 Answer

Swapping an edelbrock 750cfm to a 500 or 600

Im considering swapping out the 750cfm to maybe a 500 or 600cfm. So would the existing manifold work? The 750 seems to be little more than what the motor needs..This carburetor is goin on an 84 chevy 305 by the way.

    650CFM on a hot street engine. Anything more is redundant for street use. (Supercharger/s, Turbocharger/s, are next )

    Sorry. It depends on the Intake Manifold. Quadrajet style intake? Yes. The difference is in the jetting of the carburetor, (Jet's and Needle's), and the size of the Venturi's. Nothing to do with the Throttle Plate. However, you cannot put a Squarebore carburetor on a Spreadbore (Quadrajet style), manifold, without an adapter plate. (Just in case you have a carb that old )

Yes the existing manifold will work. 750 is WAY over carbureting the engine you have here.

SOURCE: 383 Stoker Chevy dies when I put it in gear

That converter should make stalling less of an issue, not more. (stall speed is higher than stock) Make sure that you have the cam degreed in properly, that you have the timing set properly (I'd use 8-12 degrees to begin) and make sure that you have no vacuum leaks.
With a stock converter, you shouldn't use any cam with more than 220 degrees duration...With the higher stall converter, you may get a few more degrees leeway. Also, the carb is too small for the application...should have at least a 750 dbl pumper or larger on there depending largely upon the car weight, gearing and what you have as far as intake and exhaust. (header diameter, length and design)...This should have been all figured out on paper before spending a dime for parts...Biggest mistake I see is people putting "mis-matched" parts together and expecting it to work (everything needs to compliment everything else)

1986 dodge with a 2001 360 dodge magnum motor 600cfm edelbrock carb, air gap edelbrock intake. new plugs (e3s) new wires new coil new ballast.. is all in time.. wont start help


Are you getting spark? You've put a 2001 engine into a 1986 body. The 2001 engine ran with an engine control module (ECM), the 1986 doesn't have that. The 1986 probably has an electronic ignition module that works with the 1986 coil and 1986 reluctor/distributor. You may want to compare the two distributors and the two coils.

Only 4 cylinders working


Hi,
Yep that could be it, once you have done this run a vacum gauge off the manifold to see what reading you get also.Check that the spark and fuel delivery systems are running correctly just too eliminate those 2 areas.

Have you considered making an adapter plate? You can use a piece of 1/2" aluminum plate, drill it out to match the carb venturis on one side and the manifold plenum on the other side, them blend them together. bolts going into the manifold can be used to fasten the adapter to the manifold using tulip bolts that will be flush when installed. Drill and tap your studs for the carb using the gasket for a template. of course you need to use two gaskets, one between the plate and manifold and the other for the carb. It takes a bit of work and patience. I use a die grinder when I need to make one. Kerosene is useful for keeping the grinder free of debris.

If i buy a new motor does not include fuel injectors


A new or re manufactured engine will not. A used engine might. New or manufactured engines (long blocks) usually require the swapping of intake manifolds, exhaust manifolds and all the other sensors etc. Used engines will usually come complete but still may require swapping of parts in order to be used with your vehicle or because those parts have been sold.

I am going from a qudrajet carb to an Edelbrock 600 with manual choke. I am not sure how the linkage switches over. I am working on a 1985 chevy 4x4 with a sb 350


If your staying with the stock intake manifold the edelbrock wont fit unless you install a adapter plate.And i would advise you not to install it will not seal properly.I would install a edelbrock intake manifold and carburetor as a matched set.You can purchase a edelbrock carburetor and intake manifold from advance auto parts that's designed for your vehicle.
