forged 347
how strong have you guys made your 347's? im planning on running a 100shot on it when i go out and play on the street. and when i go to the track i plan on running a 200shot. the car is usually raced once or twice a weekend if not more. but i usually only go to the track once a month. if anyone could give me any input thatd be great .

With forged rods and pistons, that will be no problem. I would recommend going with a Wiseco piston since they will come with a stainless/napier ringset and a good forged h-beam rod like a Callies Compstar. Depending on the head you are going to run, you want to get the compression up around 11:1 since nitrous likes compression! It will make a little more power for you. However, with a 200+ HP shot, as long as your tune-up is on, you shouldn't have a problem out of the parts. As always have a good experienced builder who is familiar with LS engines do the assembly!
