Carb Suggestions
I currently have a Holley 4779-3 750 Double Pumper. I have been fighting a lean bog both while cruising and off idle. I have fiddled with squirters and the pump cam and have improved it, but not eliminated it. It has been suggested that I need a vacuum secondary, which I am open to the suggestion of. I also do not have an electric choke which I would like. So the model I was looking at is THIS ONE . I have had this car for 3 1/2 years and never even came close to a track, but performance is important to me, but driveability is very important also.
It is a 383 with vortec heads, a XE274H cam and an Air Gap Intake. I have a Hughes 3000 RPM Stall Speed in the TH350 and 3.90 posi rear. I have a vacuum gauge and idle around 13. Are there any thoughts on this carb? Or any suggestions?

Carb Suggestions
If you want to know what to use for a carb you should ask the Tech @ BG guy here on the Bulletin Board,he will give you sound advice.I gave him all the info on my car/engine combo and he gave me his recommendation,which I followed , and I'll tell you I'm some glad I did,my car has never performed this good!

You could also go to http://www.holley.com/ . They have an interactive carb selector. Its on the upper right corner of the home page.

I considered the Street Avenger at one point, but on a few forums I heard some negative things about the Street Avenger line. Seems like the 80508 is the way to go! Any other opinions?

Thanks, but I'd like to stick with a Holley. Right now I just can't make up my mind between the 80508 or a 770 Street Avenger.
