thanks for the info..he does have a nitrous kit but need more stuff to install it correctly on his lt1..it was a nitrous kit from a 04cobra and has the extra solenoid to make it wet..but i guess the TB plate or something he needs and would just be more then he wanted to pay to have it installed...but this might be a new option with the rebuild..would you recommend the standard oem pistons or forged internals?..im unsure of how strong these components are..and just trying to help him ask the correct ?s during the rebuild...
