To Turbo or Supercharge

I've thought about going with a home brew draw thru on my recent/6 build. True, measured, 8-1/2:1 CR, ported and shaved head, oversized SI valves (1.70/1.44) Oregon 819 cam (no overlap with this cam) and Aussie head gasket.

this is in a D150 with a 727, and 3.21s different purpose than OP. Was thinking about 8 lb or so limit. "Hey, it's a truck"!
Was looking into possibly using a turbo off of a lebaron or shadow. Yeah smallish I know but I'm not building a racer.
