I have an 800 cfm double pumper Holley I was thinking about changing the main body on it to an HP style, to use on my Vega with its 400sbc. Car is auto.
Before I do that, I want to figure out what is already on my motor. Only numbers I see on it are 2762, I searched the web and Holley site with no luck on that number.
Carb seems fine, needs a good cleaning, but seems set up a bit unusual to me. There is a screw in the linkage to make the secondaries open very quickly, if I blip the throttle quickly at idle or try to nail it from standing, it bogs. From standing to get it to not bog I have to rev to about 2-3k rpm while holding brake then it will take off without a bog.
I've looked at it numerous time, even put on a new fuel inlet lines, but never really noticed it does not have a rear metering block or secondary pump. Is this a mod for drag racing, and because the car has NOS setup and is an automatic?
I also never noticed it has annular booster. Could it be a 9379, 9380, or 9381 750, 830 850 cfm repectively?
This other carb I have laying around is in good shape, I took it off a big block car I have, very little mileage on it, just though I'd try it to see if Vega ran better with a different carb. But maybe its not worth spending money or time.
Here are a few pics of carb. Thanks for opinions
