Change the rod bolts out for some good ARP, especially if you are giving it the Nitrous shot. Also check out this web page: Chevy | Camaro | Firebird Reviews, Performance Parts, Modifications - LS1Tech.com, huge amount of information there and lots of guys that willingly share info just like here. Much better choice than the big Caddy. Those are great truck motors if you want to build a tow rig.
