Re: 85 C10 LT/6L80 Frame off build

Love the setup(s) and the truck is clean as hell. excellent work. I found a 6.2 and 2wd 6l80e, with harness, accessories, and driveshaft, out of a 2012 silverado with 116k miles for 5 grand. Been thinking all day about changing out my cammed L33 and 4l65.
I read some people saying the 6l80 isn't as strong as a 4l80 and can't hold much more than 400hp. Any concerns with yours? or are you staying relatively mild with the LT?
