An LS1 stock rotating assembly or the weight of the crank/pistons/rods. I've looked and all I see is that its either 'a little' lighter than older stuff or etc vague responses. The full rotating assembly weight is best but not necessary, the crank is hollow for the oil but I'm still not sure what it weighs. Anyone ever checked the weight of these assemblies?

Piston: 434g, Pin: 126g, Rings: 44g, Rods: 608g, Rod Bearings: 46g. Crank?, but the stock LTI crank is 53 lbs for comparison.

Thanks thats exactly what I was looking for.

Going from memory, I think the new LS1/LS6 performance book lists the crank's weight at 143 lbs.

FaSS Blac, thanks for the info! If you can weights for other engine components, please pass the info or a link along.
