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.

Navy Blue Metallic- `98 Formula M6 HdTp
Search is your friend
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.Craig

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.

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