    What is the difference between the lsx motors?

    Can someone explain the differance in detail what exactly each ls motor is.

    ex. LS1= 346c.i around 350hp 6bolt main, aluminum block/heads. 10.0/1 compression...

    And what is the differance between the ls6 and the ls2? They are both 6.0L and they both produce 400hp.

    Are heads, cam, intake.... all interchangable between the lsx motors? Like with old small block chevys you can put 327 heads on a 350.

    Thanks.

    LS1 - 5.7 - 350HP
    LS6 - 5.7 - 405HP (01 only 385HP)
    LS2 - 6.0 - 400HP
    LS3 - 6.2 - 430HP
    L76 - 6.0 - 367HP (87 octane)
    LS7 - 7.0 - 505HP

    Most parts are interchangeable but LS3, L76 and LS7 have different head and intake designs that will not swap to the older 5.7 engines.

    So the ls1 and the ls6 are both 5.7l? Do they have the same block?

    Is the bottom end of the two engines identical?

    bottom end of an LS6 is different. The block itself for the LS6 had better bay to bay breathing in the crank case. I have a stock LS1 and an LS6, tore both down to shortblock form and you can tell which one is better.

    Some of the '02 LS1 f-bods came w/ LS6 blocks.

    What did ls3 come in? And what about the l76? Is that the truck motor?

    The LS3 is the standard engine for the `08 Corvette
    and the L76 is the base V8 for the Pontiac G8.
    They both may be available in diferent models of the New Camaro aswell.

    Always heard that LS1 block was a little stronger than LS6. Not sure why?
