340 motor cam

Hi again, i didnt buy that other 340 engine with the piece broken off but i found a new motor it a 70 340 bored over 60 with..292 duration/509 lift camshaft.Rhoads lifters. 8 quart oil pan.LD340 intake manifold. Is this a good street friendly motor, what carb would you put on it i have a 600 cfm holley but i think its too small.

Thanks for your input
