I'm not sure, but I think a LS1 is a 350, even though it is labeled as a 5.7 liter, and 5.7 only measures out to be 346. My dad works at a GM dealer and the way he explained it to me was most auto makers round the measurements up. How strange would it be to call a LS1 a 5.72? You know a 305 Chevrolet is considered a 5.0 just the same as a Ford 302 is a 5.0. The liters are rounded to the closest tenth. However, I've been known to be wrong quiet a bit.
