Building a 360, new cam, pushrod length?

I'm gonna look at some other camshafts as recommended by strokerscamp, and I'll consider what you're saying Kim about trying to sell my new stock pistons, but I just don't know if anyone will be willing to pay much for them, if at all.

I'm gonna have to make a tough decision on whether or not to eat a couple hundred bucks wasted on pistons, and just buy new ones. Then I also have to pay the machine shop to remove the rods... I don't know...
