So far, it looks like everyone is leaning towards the little engines. I kind of had in mind of using the 350, since it is almost scrap anyway. I thought about giving it a good hone job, using the open chamber heads (heavily worked over with some type of dome piston to get the compression up. I was thinking this way because the 350 stuff is so cheap. However, I am listening to everyones opinion.
I want to do it as frugally as possible and get the most for the least (just like everyone else.)
