Iron LS6? I have an early 5.3 that needs to be bored. I would like to find a set of gen 4 rods with pistons to build a 5.7. Is there something stock that I can be searching for on evilbay to find this pistons and rod combination? It will be topped with 243/799 heads.
Yeah late 2003 model and 2004 only had the floating pins and coated skirts.
The factory ones will have the tallest pin center to top height.....meaning they will pop outta the hole .007" on an un-decked block
Aftermarket pistons are usually shorter and require the deck of the block to be machined in order to tighten up the quench again; may be what you want to do anyways.....your call

Could swear I've read and heard others say the real late 03/04 LS 1/6 and LQ9 had the gen IV style floating rods. My Vette was a mid year 03 with LS6 short but press fit rods. My early year 03 Silverado SS had coated skirts but press fit according to what I read (never tore that one apart)

That is correct. The 04 model such as the Corvette, GTO, and the CTS-V had the Floating pin piston and rod combo with coated skirts.

They arent rare but can be harder to find used from an engine. We have them for $320 with rings though ;-) brand new.
We also have recon gen4 rods that have been cleaned and honed on both ends ready to go also.
Still budget friendly. Or even sets of scat forged i beam 6.100s with arp bolts for $300.
