Complete Brake Kits

[1980GMC]

So I want to get a complete brake kit for my truck. Disks front and back. I just cant seem to find a complete kit. It's gonna be stopping a supercharged 454(or 496) so I need some "WHOA" power. What company manufactures a brake kit with reasonable price and good/great quality? Rotors, calipers and all? Components right now include. DJM 3" drops spindes, and stock rear end (although I'm adding an aftermarket POSI). I'd just like to be able to stop this sucker just as good as I can get it goin.

Thanks,

Wes
