68 68 chevy C10 19210009 install and AC question

[katydude2000]

I have a 68 Chevy C10 that came from the factory without AC, but came with power steering.

I'm thinking of putting a new crate motor in it....http://www.newgmparts.com/oe-gm/19210009

What issues/things to look for should I consider? Don't want advice on a different motor necessarily....

What type of radiator to use? How about the venting/routing for the rest of the AC system out of the compressor on the kit that comes with the motor(it is using Chevrolet Performance Deluxe Serpentine Drive Kits 12497698)?

I'm sure some of you guys have put this config in their trucks.....school me!!
