These are some really neat sounding ideas, getting that many more cubic inches out of a 261 and 235.I'm working on learning more about the machine work and the precision instruments for getting everything exactly right. I feel like right now I know just enough to be dangerous, and I put too much faith in machinists to get everything right for me to assemble. Especially on the "non stock" things.
I've heard of people boring out Ford model A engines (they're basically half of the flathead V8, right?) to fit Farmall M tractor pistons, which I believe have a 3.8 or 4" bore. Not sure how long they lasted, but heard they made a fast coyote hunting wagon.
