okay so I been workin on buildin my ls for a while head is done so now on to bottom end my question is all 3 blocks I have are spun bearring (rod) now every one I have talked to says I can't build them for boost cuz it will spin a bearring again. If I have the crank turned and a line bore on the block will it be okay? Obviosly this is the first buil I have done any help would be appreciated
