OK i just got in touch with a guy that has a Block bored .040 over with matched OEM style pistons and rings, OEM rods, and ARP main studs, and all clevite 77 bearings, he wants $275 for everything and if i did get it i would have everything Cryo treated by Deep Freeze Cryo. Now for the questions, would this be a streetable/reliable setup, and how much horsepower would this setup be able to hold?
Is .040 TOO much?

well i would have the rods heavy blasted and lightend. the bottom end would be good for a solid 500rwhp. just note your pistions are the only "weak" link. just make sure it has a good tune and it should last at 450-500.
i would also upgrade to arp rod bolts to, for like 50 bucks why not.

Just be aware of this general rule on boring: http://www.supramania.com/forums/showpost.php?p=180360&postcount=10
...to a small extent. like SC said in his post, you wanna value what youve got cause it won't last forever. the smarter route to make more power is just upgrades to better supporting systems like cooling, fuel, air, exhaust. basic import theories on tuning, making power through boost instead of displacement
On the parts you get cyro'ed, make sure you check clearances...cyro tends to shrink the part a tiny bit. In fact, I'd re-check every clearance and spec on the crank, rods, and pistons. The suggestion for ARP rod bolts is sound advice...get ARP head studs too 
OEM style? Did he get Ebay pistons? I'd look into that. Because I believe that Toyota only comes in .020 over.
I always try to go the bare minimum in bore size that will give round straight true bores as this leaves material for another go if something goes wrong
