What has to be done to an iron LS block in order for it to handle 700-800hp with boost? Which block is better 5.3 or 6.0 for a turbo build? Is it more cost effective to just get the LSX block from GMPP? I am planning my build for my LS swap so I can order parts while I am deployed. I want a turbo LS under the hood that will last and be powerful as hell.
