GM's choice to continue with an overhead valve engine family was controversial at the time the LS was introduced. Such engines were seen as low tech and outmoded compared to the smaller and more powerful overhead camshaft engines favored by Asian and European manufacturers, and indeed, both GM and its domestic competitors Ford and Chrysler had or would introduce overhead cam V8s of their own. However, the overhead valve layout did present some advantages, two of which were lower overall height (compared to an OHC engine of similar configuration) and lower center of gravity; both of these were advantageous for the line's use in the Corvette, whose low hoodline precluded the use of an OHC engine. GM also made extensive use of economies of scale for the LS: with the exception of the 4.8L and 7.0L engines, all variants used the same 3.622" stroke (with most of those variants using the same basic crankshaft casting), the 4.8L and 5.3L variants utilized the same block casting, and several variants used the same length connecting rod.
