LS6 Question of the day (floating wristpins)

[torkman15]

When did GM start putting full floating wrist pins in the LS6 engine? and do all LS6s get full floating pins? Just ZO6 vette LS6s? Just 2005 CTS-V LS6s? I need two pistons w/rods to put my backup engine back together, any ideas? Thankyou, Tom

GM started using a bushed connecting rod with a full floating pin in the LS2. There may have been some LS6 engines built mid year 2004 that also got the new design rod and piston.
