Mark:
I was looking at doing the same thing, and for a daily driver, seems like it would be hard to beat the ramjet 350, especially considering that a good aftermarket FI system will set you back 3 grand. I know it isn't an ultra high performance set up, but 350 horses and 400 pound feet would certainly work for a daily driver, especially for under $5,000 complete with fuel injection.

Wish I could tell you I have experience with one of these engines, but maybe someone else here can offer some insight.
