Will a Stock 489 handle 700hp?

I voted no because 700 horsepower is hard on any rearend if the car is raced often enough. Not 700 horsepower and I’m not sure which 8 3/4 center section my son is running but he raced weekly running from 10.11 - 10.30’s for 3 years with zero issues. 3200 pounds, caltracks, transbrake use, and radial tires. Housing is not back braced, stock caps, spool, Doctor Differential axles, and 4.10 gears. He tried to put new gears in it every three years. His last set had three plus years on them and a racing Friday needed them for his 9 second big block footbrake car. They have 2 more years of limited racing on them and are still going strong. He hopes to update to a fab 9 inch in the near future. Neither car is probably near 700 horsepower but that’s not to bad out of what some consider a junk rearend.
