Ill try to help you out here, stock cast pistons and rods are no good for nitrous, if you want to build a motor that can handle all of that then you should get a forged crank and a good set of rods with arps or a good rod bolt in them. Judging by the last post, you wont be able to buy a forged crank let alone a whole rebuild kit for $500 or less. If your looking for a little more horse look into a stroker kit for your motor, i posted the previous websites for your other question, you can look for a kit there, you will have to have your block clearanced most likely, I would say a stock motor could handle a good amount of horsepower but you CANT turn high rpms in it or you will be getting a new crank. hope this helps
