Compiled engine component and accessory weights? LS1/LS6 I've looked around a bit but haven't found anything like this yet.
I'm looking for LS1 (or preferably LS6) components and their weights including accessories.
Please post up what weights you know, and I'll update the post. Also please post corrections as necessary.
Thanks!

Would like to add...
just happen to be sorting some things out this evening and noticed a few floating pin rods among my mix that had different features, so I got the scale out and they are around 10 grams different in weight. They are most notably different at/just above the parting line on the smooth side of the rod (non dimple side). The heavier rods are out of a GTO LS2 (all 8 match), the lighter ones were in a mixed bag of light and heavy rods in reman motor (3 of one 5 of the other, yikes).
My scale is a kitchen scale, not terribly accurate, but at least repeatable to the point that I can claim these indeed have different weights.
For other references, stock LS2 piston with OE rings, pin, clips and a little carbon is 662g. And coincidentally, +.030 LQ4 dished pistons with rings, pins, clips, and a little carbon are 664g.
And finally, 010 under rod bearings (thicker to make up for -.010 machined crank journal), are 4-ish grams heaver than STD bearings, 42g versus 38g for a pair.
