Will a Stock 489 handle 700hp?

I run 742 carriers 456 430' and 488's with spools and GM style yoke. Slick tire with over 700 HP All those old B-body Hemi's and Max wedges ran 742's wheels in the air from 62-66. There were no Dana's .

I never did care for 489 carriers, They were as good as the cone style sure grips they came with from 69 -72. The only reason I would use a 489 would be to make a muscle car come with what they had. Remember most of them came with F70 14 bias tires.

The first 8 3/4 rear I scattered was a 489. I have not broke a 742 to this day. 741's the pinions break with slicks. My first choice of a rear would be a Ford 9 inch. Three pinion bearings. one behind the yoke, One in front of the pinion gear and one behind the pinion gear. Pinion flex is the weak link that makes them break if they are not set up right. The teeth need to engage deep. I have several chunks as spares so I am staying with what I have 8 3/4, easy gear swap for 275-315 class 1/4 -1/8 mile. who can carry spare Dana's in the race trailer.

Billet caps
good axles
good gear sets
GM style yoke
Proper pinion angle
good stiff front segment springs

Less reciprocating weight then the Dana.

This is just my opinion for spending as least as possible and going racing with a 3650 lb automatic car with a 5500 stall. Same rear since the car was built many many years ago. And it will carry the wheels if wanted.
