Will a Stock 489 handle 700hp?

Kind of irrelevant but goes along the theme of what everyone has been saying... my stock rv 360 with aluminum intake and headers backed by a stockish 727 has yet to kill my 7 1/4 behind it... a rear end that has a reputation of breaking if you look at it wrong. I keep small tires on it and give it hell and it has lived for the couple thousand miles that Ive driven it (and an unknown amount of miles put on by the previous owner). Point is, on the street with no sticky tires that 8.75 should live for a LONG time, but once you start giving it big system shocks and hard launches with stickys, then you will find the weak links quickly.
That being said, plenty of guys have made their 8.75s live long lives behind race dedicated cars once they got rid of the weak links. A buddy of mine has run a 8.75 in his front engine dragster with 2000+ horsepower for years years with no issue. The real question is if you want to put in the work and time to make the 8.75 work? Or do you just not want to ever worry about it again with a heavier D60?
