Kelsey Hayes on 71 demon?

i was getting my 71 demon preped to go on the rotisserie pulled the front wheels now i had just assumed that it was a drum brake car because its a base car with /6 and power steering only no power brakes. pulled the wheels for the first time and bam disc not drums. is this some thing that a p/o put on or could it be factory? also the car does not have sway bars..
is it common to find Kelsey Hayes setup on slant 6 demon's? i am putting a small block would these work or are thay too small for the added weight.
