When is it too much power for the street?

too much power? Ill give you my example: 451 Stroked 400 block, 590 lift cam, CNC ported heads and 2" headers in a 65 Barracuda with 215 rear tires and a 3.91 rear. It was difficult not to spin the tires in any turn and on take off with a 2800 stall convertor, out it came. Of course the tires were the real crippler, but a 2900lb car doesnt help traction.
