Stock and big power - What's going to break next?

Hi guys!

My dad and I have been working together on our trucks for a few years. I have a '66 C10, and he has a '64 K10 Stepside.

Recently he finished up swapping a bowtie specialties 350, which has been built and bored out to a 355. It makes somewhere in the neighborhood of 375-400 horsepower.
The rest of his truck is essentially stock.
The big question is, can the other components (transmission and rear end) handle the power? Obviously brakes and whatnot should be upgraded, but just trying to find out what else we need to add to the list.


Additionally:
My truck has a TKO500. I love it, it's awesome. We were talking about the idea of upgrading his transmission to a TKO500 or TKO600, but I don't know if it being 4x4 would allow for that transmission or not. Can a TKO be hooked up to a transfer case?


Thanks guys!

Re: Stock and big power - What's going to break next?

You have a 12 bolt rear, they will easily handle the power you are putting to it. The TKO will also handle the torque just fine.

On the 4x4, consider the NV4500 with the transfer case will work great and handle anything you can throw at it.

Good luck!

Unless it has been changed previously, your dad's '64 K10 will have a divorced transfer case, likely a T221.I would upgrade to either a SM465 or a NV4500 as clyde65 said, coupled to a NP205 transfer case.
