360 build power estimates

Nice advice Every one and thanks alot, and for the Holley street avenger 670 they are absolutely lovely. I personally have never had one on my car but i just finished installing one on my cousins 68 Impala with a 350. Not my choose of car Chevy "No No". But I would have to say after a lil tuning to it to take out a low idle stumble, the Chevy ran like a beast. The car had a Holley Dominator 700 or 750 on it but the street avenger gave him tones more power over the old carb. When I call him to pick the Chevy up he didn't beleave me when i told him this car ran like a lil mini race car. But i would have to say the old chevy ran good with the 670. But i figured that the 360 need a lil more cfm being it has a larger stroke then the chevy 350. Oh yea i know the Street avenger is suppost to be a bolt on out the box carb, i would say u for a person who doesn't really care about gettin the best possible performance and just wants to ride u can bolt it on out the box and ride. But for the speed junk's it'll need a lil tuning.
