    How many CI is the LS2?

    So a buddy and I have searched the internet and were wondering what cubic inch the new 6.0L LS2 is? 3 different links on google turned up 364, 366, and 402. are there two different variants of the LS2?

    GM Lists the production LS2 as a 6.0L / 364CID engine. With 4.00" Bore & 3.62" Stroke, actual CID is 363.922" = 5963.58 cc. So with the rounding up you get your 6.0L & 364CID #'s

    Rainman, thanks! A couple of sources had said the LS2 was a 364, then a 396 so I was getting confused.

    The 396 and 402 are aftermarket stroker motors.

    396 = 3.905" bore LS1 block x 4.125" stroker crank
    402 = 4.000" bore 6.0L iron truck block x 4.000" stroker crank
