when did GM go to floating Pin
Well,it a little complicated, to say when the entire LS based engines across the entire line up. But the first to receive them were the LQ9 in the Escalade going all the way back to 02-03. Which precedes rest of the line up by a least 2 years .
It is diffcult to say exactly when they started across the entire line. But they started puting floating pin in most by late 2004MY. But if you are looking to buy a engine and want floating pin start with a 2005MY to be on the safe side. With out knowing the production date of vehicle , 2004 will be a hit or miss.The excemption is the LQ9 which I stated earlier.All Gen IV will be floating pin. LS2 and LQ9 basicly the same piston and rod.

Same. Car stuff 2004+ (model) all have seen it. Truck stuff on 2003s, not sure on 2002 but haven't worked on alot of them. I think it might be when they started using the 243/799 heads on everything non sqareport. With the older head casting motors I think yo me have always had the pressed pins/non sym. rods internals.
