72 C10 Rear end question

[Yeahsmitty]

Hey y'all,

I am doing a 6.0 ls swap in my 72. My question is, will i need to swap rear ends because I'm adding more power? I am going to put a stock 6.0 with a 4l80e behind it.

If i should swap it, what should i switch to? I know almost nothing about rear ends.

Thanks for the help!

The 402 big block installed in these trucks made more torque than your ls 6.0ltr..
so no need to change the rear end..
might want to change the gears depending on what it has. and what you want out of the truck. and if you need lsd /posi if it doesn't already have it..
