Default Forged 346 pistons/rods??

I am looking to build my car to handle a good shot of nitrous. However, I am having trouble finding stock bore forged pistons? Right now I just have a ms3 cammed ls1 (mods in signature) and I put a 150 shot through it. I just want to build it for nitrous so I dont have a gut wrenching feeling at the back of my throat everytime I spray.

anyone know who sells them? Like I said, I just want forged rods and pistons for nitrous, and arp rod bolts. I would like to get around 650-700rwhp after all said and done on a 250 shot. I already have a ported ls6 pump and the fuel setup to get me there as long as a moser 12 bolt.

im looking into doing the same thing as well. i dont think they make them stock bore, but like a .005 over.

guess in my build im going with some diamond pistons -2cc valve reliefs, rings gapped for nitrous 2-300 shot, steel napier ring, and callies compstar rods.

most vendors can hook you up. also ask if you can use your block and crank to save some money.

i think im settled on a newer vendor we have, ah...cant remember the name, they're in topeka kansas. using my block and crank with that stuff in it was i think 26-2800...

whenever you change the pistons and rings, you have to hone the block so that the new rings can ceat probperly. when they rehone the block, you just tell them what size bore you need according to the piston that you order. honing is not that expensive (most shops will hone up to .010" over). its when yopu staret boring the block that it gets more expensive. also, the bores are not perfectly round from the factory, so you will benefit by getting a good oversize hone at a reputable machine shop.

there is a pretty good machine shop literally within walking distance from my apartment. Maybe I will swing in there soon and just see what I come up with, for numbers and what not.
