[68chevelle]

520 at the wheels would mean hes pushing about 630-650 at the fly. honestly i would just have to say hes BSing you. it had better sounds hella mean with over 600HP. it would probably sounds pretty lopy from the cam too. with the wheels he has,(they dont look overly wide) he should be able to spin them all day without a problem. but it also has to do with suspencion. just ask him to light up the tires, without using his brakes at all. he should be able to lay on the gas a roast them for a long time. he might move especialy if its a open rear but he should be able to spin his tires all day long. but like i said, he probably doesnt have that much power. if he could get really good traction off the line with that much power he should be able to pull the front end off the ground.
