Can someone here check my sanity? I posted over at the Gen IV internal section looking for a actual weight of an LQ motor. Consensus is that it weighs 93 pounds more than the LS1 motors, so what does a complete LS1 weigh? I did a bunch of searching and there are a lot of numbers flying around. I'm guessing 434, thoughts?
