5.3 crankshaft
5.3 crankshaft My LS1 spun a rod bearing and damaged the #1 rod journal real bad. The machine shop says they should be able to reground the crank .040 but wants $400+ to do so. I found a stock crank out of a 2000 5.3 Silverado without any damage for $100. I'm adding forged Eagle rods and forged pistons so either crank would have to be balance to go with the new rods and pistons. Does anyone know of a good reason not to use the 5.3 crank and save myself $300?

Definitely should work. Honestly though, the crank is a big "while your in there" part. Might be able to find a good deal on a complete rotating assembly and you'd have the peace of mind of a new, stronger crank.

You can use a 5.3 crank but the LS1 cranks are gun drilled, the 5.3s are not. And there is no need to get a new crank unless your are planning on making some crazy power, there are plenty of ls cranks getting to 800+ rwhp. Like what S10xGN said, make sure you completely check over the entire crank before installing it.
