ok here's the deal. i threw a rod bearing in my b16. i have a complete built top end, and a complete stock bottom end. this is why she threw the bearing. now the problem i am faced is what to do with it...should i put in a lightweight crank (where can i find one???) or should i stroke it? what should i do from here? whats the cheapest and best route? where can i go from here.

i know of a ls motor, i can get ahold of its bottom end. only thing is can i do that transplant? b18 crank n stuff to a b16...it would be my cheapest bet if possible.
