Just wondering what the opinion is on this Carb? I was going to run a 800 cfm Rochester but this carb seems much simpler. Was running a edelbrock performer 750 CFM. Not that I do not like Holley but I would like some gas mileage.

 

The Thunder AVS carburetor is the same thing as the standard Edlebrock carburetor except you can adjust the secondary air valve. If you currently have a standard Edelbrock carburetor that is working fine then just keep it. No need to fix something if it isn't broken.

 

Looking at the specs the jets and metering rods are all significantly bigger than the 750cfm performer Carb. I am going to go with this carb because you can adjust the secondary air valve. With Edelbrock heads on the car I am sure I can use more air flow. My car fell flat after an 1/8 mile with the 750 CFM performer. Keep you posted

 

No better or worse than any other, in a given application.

If that is what you have, use it.

If you were to "do the math" you would find that the fuel supply will be the same at any given air flow.

Look for a restriction (clogged filter?) or a break in the fuel supply system. Next, check (with a gauge) the fuel pressure at the pump.
