I wonder what the optimal bore would be on that block. I'd love a bit more torque while keeping the cheap gas option.

Because of the oil and coolant passageways you can't really bore it out all that much. Not even to 3.5L without risking it cracking. But you are right, stroking is more difficult but the only real way to increase displacement.
If you want crazy power, a turbo setup will get you there. I've pretty much at the limits of the TRD supercharger now. It builds boost but just is so small that it doesn't flow a ton of air unless it's spinning at insane RPM's, which at that case heat really becomes an issue. I've got a few more tricks up my sleeve though like changing the final drive ratio to 4.88 and re-doing the exhaust and we'll see how it drives then. If I could go standalone that would really change things though, the ability to advance timing would gain a lot of power too.
