340 or 318 turbo

I have a 1972 Dodge Dart with the 318 running engine, just picked up at 340 from Craigslist 1973 low compression 1967 Dodge Dart waiting for small block. I would like to build the turbo car as long as I remember. And this didn't help.

When I get a chance I'll go ahead and get the:mumum: parts list on here and maybe we can get some good ideas going here.
