The idle speed and idle mixture are the first things to adjust and are very easy. If there is an off-idle stumble or a bog, you'll need to make adjustments to the accelerator pump and possibly the power valve to suit your engine. Here is a link to a Holley manual that explains it in detail: http://www.holley.com/data/TechService/Technical/Carburetor%20Tech%20Info.pdf
from my experience the 750 cfm will dump too much fuel you should go with a 600 cfm. i prefer the holley. you should only go with a 650 or 750 cfm if you have 400 horsepower of more.
A 2-plane manifold such as the Edelbrock Performer or similar would be a good choice.
Yes, you can adjust the accelerator pump on a Holley 600 carburetor. This adjustment is typically made by changing the pump lever's height or by swapping out the pump nozzle size to alter the fuel delivery. Proper adjustment helps improve throttle response and prevent hesitation during acceleration. Always refer to the Holley manual for specific instructions and settings for your model.
600 cfm will be enough for that engine.
Carburetor manufacturer's (especially Holley) are very good at helping their customers select the correct carb for a particular application. Depending on how the 305 is to be used, a 600 cfm is probably about right unless you intend to routinely rev it over 7000 rpm.
600 cfm no 1406.
The stock carburetor on a 1987 Jeep Wagoneer with a 360 V8 is typically a Holley 2-barrel carburetor, specifically the model 5RHA2, which has a CFM (cubic feet per minute) rating of approximately 350 CFM. This rating is designed to provide adequate airflow for the engine's performance needs while maintaining good drivability and fuel efficiency.
600 cfm should be just right for a stock or slightly modified 350.
The holley has more cfm`s cubic feet per minute than a regular carb.and it also puts double the fuel into the intake faster than a regular carb.
how do you adjust the float level on a 650 holly single pumper
The timing set degree for a Holley 600 CFM carburetor, such as the 370 model with a 2-barrel configuration, typically refers to the ignition timing settings rather than the carburetor itself. For most applications, a general guideline is to set the ignition timing between 10 to 14 degrees BTDC (Before Top Dead Center) at idle, depending on the engine's specifications and requirements. Always refer to the specific engine manufacturer's recommendations for optimal performance.
The Holley carburetor model 8849 is a 650 CFM (cubic feet per minute) carburetor. It is a popular choice for high-performance applications and is designed to provide efficient fuel delivery for various engine configurations. The 8849 model typically features a vacuum secondary design, allowing for smooth operation and good throttle response.
