Needs some wisdom thrown my way.

Before your block is bored have your machinist check the main bearing saddles for round and alignment . While he is there have him check the head surface for flat and square with the main saddle centerline . After that , bore the block with plates . Money well spent . I recommend forged lightweight pistons because of their toughness but hyperutectic pistons are o.k. for street . "LY" rods are fine for moderate performance . Just have them rebuilt . BALANCE everything ! Iron heads are o.k. with mild bowl work . I suggest a MP cam with .488" lift . great all around bumpstick . Factory valve train , rockers and pushrods . With this bottom end upgrades are easy-peasy .
