Carburetor Help

[TheGreatWhite]

ok so shortly down the road i will be buying a carb for my engine.i dunno if you guys wanna know but im gonna list the work done to it so you have a feel for where im at. its an 89 302 bored .030 over. Speed Pro forged pistons,Eagle Forged rods,rotating assembly balanced,polished crank, frpp E-303 Cam,FRPP Hardened pushrods,FRPP Roller rockers,stock heads were cut and had a three angle valve job with new valve springs, and an edelbrock performer rpm intake. ok so i also plan on running a wet nitrous system somewhere around a 100 shot or so. i was wondering if i would have to go bigger with the cfm size of my carb due to the nitrous. obviously im gonna go with a bigger cfm than stock but would i have to go even bigger to compensate for the nnitrous?? i was looking at the Holley Street Avenger probably 670 cfm. would that be good? Just looking for some advice before i make this investment. Thanks guys

If I had to buy another carb I think I would pony up the little extra cash and get a Barry Grant speed demon. They're top notch pieces. I would think something in the 650 range would be good for you so it sounds like your in the right ball park there.
