Hello i have a few questions concerning building an all motor monster......would it be better to build up a ls block than a GSR???....im talkin resleeve, pistons, rods the works.......i understand that the ls block will give a little more cc's displacement than the GSR......i plan on overboring to 84mm or 85mm......i also understand that on the gsr block they have pistons squirters and a block girdle.....was wondering if it would be better to have those things on or if they will be removed it i was to build a GSR block???.....thank you and have a nice day!!!
