maybe we should post up some general info in one thread on the gen 3s such as rod length, bore/stroke, stock valve sizes, stock chamber cc's, and the like. will make it easier for guys trying to stick with GM parts. heres what I have so far.

4.8 LR4 = 294ci (3.779 bore x 3.270 stroke)
5.3 LM7 = 325ci (3.779 bore x 3.622 stroke)
5.7 LS1 = 346ci (3.900 bore x 3.622 stroke)
6.0 LQ4 = 364ci (4.000 bore x 3.622 stroke)

whatever you have post it up.
