alright i'm looking for a 351w(71-74) and a 4r70w trans


my question is: is there a rearend that would be better than the one in the car? i would be rebuilding both(31 spline axlesand rebuild trac loc) i'm just wondering if theres one that would be stronger and more reliable with more hp.

how much can the stock rearend handle?

just questions to be thrown out there.
 
I've heard that the 8.8 rear end in our cars can be made to handle lots of power, with the right amount of money in it. I have also heard that the 8.8 would be "better" because it is lighter than a 9". Basically the same power handling ability, just in a lighter package.
 
You will lose the ABS function with the 9 inch. The 8.8 can take a ton of power if built up. The big advantage of the 9 inch is the carrier design. You can have several carriers setup with different ratios and quickly (relatively) change between them. If you want a super strong read differential, check out a true Dana 60. I think the ring gears are nearly 10" in diameter on those.
