well i called up DSS today to order my block, and i told them everything Pete (yellow5.0cobra) and they told me since i am upgrading everything for a supercharger, which will go on sometime in the next year. i might as well upgrade to the level 20 block, otherwise they said that i might crack the block, it's 300 more for the upgrade, should i do it or not? is it worth it? thanks
line mains and such?
