i just got a new carb for my car .. the holley street avenger 570 cfm! wanted to know what i need to put it on. and if it would need someone to tune it or if it was good out of the box to drive untill i could get it tuned?

 

The setup in the box will get the car started, but it won't run the way it should. You'll need to check the carb over to make sure the linkages are adjusted properly and the external bolts are tightened.

It would be a good idea to purchase a book on how to tune a carb, as it is fairly easy to do. Finding a mechanic that can do efficiently is not so easy.
