Can stock rod and stock crankshaft handle the power?

I'll say this, trying to not get myself in trouble. My step dad has a Shelby GT with a Shelby supercharger added, some other goodies, it's easily making 500hp. After the supercharger was broke in early in the morn with no traffic he hit it for the first time. I honestly think that's the last time he ever put it to the floor, second gear at 35 MPH he swung across three lanes, good thing it was early in the morning or there would have been oncoming traffic in those other lanes. Point is, that is a car with a real 500HP and modern suspension, if the OP thinks he needs more than that in a 79 Aspen..........
