Finally got some money saved up to get a new carb, but having problems deciding what to go with. Specs of my car is in the sig, and i will be putting on the xcellerator intake as well in the next few days. I've narrowed it down to : 1. Holley street avenger 670 ($320). 2. 650 speed demon ($400). 3. 575 speed demon ($400). 4. 625 road demon ($340). There was also some other company i remember hearing about, for some reason im thinking provac maybe? These prices are for new on ebay, but if i find a good deal on used ill jump on that. Any opinions?
