I believe rod lengths are the same for both. Bore is significantly smaller in the LS1

Theyre not even close to the same piston. Everything except the 4.8 and 7.0 have the same rod length. The bore is what is different between most of the engines. Shops that have things labeled LS1, LS2, LS3 dont know what theyre doing. LS3 bore is 4.065, LS1 is 3.898. Stock rod length is 3.622.

Umm the bores differ, the architecture and dimensions of the block are the same.

What do you think determines the compatibility? the SIZE.
Throwing an LS1 piston into an LS3 block would be like throwing a hot dog down a hall-way.
