It's been a while since anybody has asked anything on this, but I know people have asked about it in the past. I found a neat little site on turbocharging a carbeurated slant six using junkyard parts and a little creativity. The information contained is easily converted to the 300/240c.i. inline.

I'm going to look into a turbocharged 240 with a t03 turbo off of a ford 2.3 turbo. I hope this helps somebody else as much as it helped me. The site is at
