Swapping to LS6 crank - rebalance? I'm putting a low-mileage LS6 crank into my '98 vette motor. Do I have to rebalance everything for the new crank, or should it still all be balanced the same? Engine has stock '98 rods and pistons.

why are you doing that? ls6 crank and ls1 crank is the exact same thing. You didn't buy this thing off ebay did you?
Well, I'll assume something happened to your stock crank since you're changing it, and yes, you should have the entire rotating assembly balanced.

Yeah, it's out, actually all disassembled. It was more of a hypothetical question. I was just trying to see if there was enough difference between a stock LS1 crank out of a '98 vette and a LS6 crank out of a '02 Z06 to need a whole rebalance. From what everyone is saying it looks like I need to get it all rebalanced. I was going to do it, but then I heard elsewhere that the difference in cranks wasn't great enough to warrant a full rebalance.

BTW, factory doesn't balance these.
What you need is to blueprint your assembly. That is all.
Measure all specs and tolerances and adjust if necessary. A rebalance is not necessary.
