carb cfm ??

[67fishfastback]

wanted some advice on carbs,i am looking at a holley 670 street avenger w/ electric choke. I have a 360 mildly built 9.5 comp. 475/494 , 220/226 at 50deg. little head work. Any suggestions??

Very good choice. I have one on my 360 that is a little hotter. I have had as small as 600 and as big as 750. For a street driven car the 670 gives me all the throttle response and driveability of the 600 and gives nothing up on the top end compared to the 750.
