which carburetor?

I've got the Holley 670 Street Avenger on my 302 with a dual plane intake, it's definitely a little too big but that size should work great on your car. Its reliable and I like it, but when you nail it and the secondaries suddenly open it hesitates for a second (used a light spring, the heavier spring didn't seem to open the secondaries much at all). I've adjusted everything on that carb and the bottom line is it's just a little too big.
A friend of mine has the Edelbrock carb on his 440 Barracuda, somewhere between 750 and 850 I'm not sure, it runs great and is very very fast, can't imagine a Holley would be any better it runs so good. If I did it again I'd go with the Edelbrock just because I've heard the street driving traits of it are better than the Holley and after riding in his car I believe it.

looking through the old posts and found this one, if you haven't made a choice yet, i reccomend the edelbrock, as i have a holly on my performert intake and have the same hesitation problems as dbiscayne has with his. i'm switching over to a edelbrock 5

The hesitation problem is almost always from too much carb. A 670 is way too much for a stock 302 but would make a excellent match for a 390 depending on the cam. Holleys from what I've seen run better times than a Carter if the owner resists the urge to go for too much CFM.
