Does anyone know the importAnce of micropolishing n balancing a crank? The reason why im asking is because i dont really know the answer to the question. I plan on building an ls/vtec motor that should be pushing out between 600-700hp. Everything on the block was rebuilt because the pistons were done and one of the sleeves were broken and this is my next step and the block will be done but i would really like to know the importance of this step before actually doing it. Im pretty sure others will also like to know the answers to this questions. The Motor Will be boosted (just incase u guys decide to ask). If you guys can please help me out i'd really appreciate it thanks!
