Swap 4.8 Rods Into a 5.3 Does anybody know if anyone makes a set of pistons with a raised pin height so you can run the longer 4.8 rods in a 5.3? I know I can spend $$$ and get a custom set made but wondered if anyone already made an off-the-shelf set for this combination.

That is a .177" difference in length and raising the pin that much in a 5.3 piston could crowd the ring pack more than desired.

Unless you are running crazy RPM it makes no difference.

I think that how much I crowd the ring pack, whether it is cost effective for whatever I am doing or whether I have combed through the libraries full of documentation on the (any engine specification) vs. rod length argument and come to my own conclusion would be my decision and really had nothing to do with the question I posted. All my post required was a yes or no response and if yes, who made the rod set. I appreciate the spirit of the unsolicited opinions and everyone "just wanting to help me out" but please restrain yourselves and just answer the question and if you don't know the answer do not post a reply.

Your question might be better aimed at someone like Summit who can give a direct answer to your question.
Most here were trying, in a way, to tell you that if you don't see them listed as a regular catalog item, it's because there is no good reason for such an item. Just "wanting to do it" is not a good reason. If there was a good reason, they would be readily available. You asking the question here pretty much says they are not readily available.

I once read about a guy who rebuilt a vintage Ferrari engine with Honda pistons because the dimensions were correct and cost thousands less. My Dad replaced the door seals on his 1964 GMC with the ones from some random Japanese 4 door car, just because they fit. Old Harley engines used to use the same ignition points as certain old Jeeps. My point is to expand your search outside the commonly known LS world.
