Dimensions are approximate outside measurements as published; accessories, intake and oil pan change them. The 2JZ figures may have length/width swapped in the source. The 5.3 LS height is left blank: the source lists 34 in, which doesn't match its own 28 in for every other LS, and we couldn't verify it.
