In need of an education..340 vs 360.

This is an interesting discussion, especially for me since I made the decision to put a 340 in my 73 Duster. I thought about a 360 since they were easier to find, but I decided I had to have a 340 because that's what would have come in it in 73. I took a chance on a motor at Carlisle last year and paid $850 for a 73 340 motor that was mostly complete. Not knowing then what I know now (and that still isn't much of anything), I didn't need most of the stuff that came with it. It came with all of the throw away things (like pistons and cam and stuff). At least I got heads, a crank, an oil pan, and the caps out of the deal. I have an intake, but we're going to put a more modern one on when it all gets said and done. Sometimes I wonder if I should have just gone with a 360, but the decision has been made and what is done is done! If I blow this one up I might go that route. :)

As part of the build, he's had to bore it 0.04 over. He wasn't sure if he could find pistons any larger if it needed to be rebuilt again (he didn't look for them since we didn't need them), but, from this thread it sounds like I should be able to find pistons 0.06" larger for it? I don't know if it will be an issue, but I would like to know in the event I need the motor rebuilt since my goal is to drive it fairly regularly.
