    New to the LS what differs the LS1 and LS6

    I havent done my homework yet. I have built a few V8 Nissan 240sx's but I used older 4 bolt main 400's and a 350. What is the difference between the stock ls1 and LS6 besides the intake. Do the motors have a different compression? heads, injectors? On my next 240 project I want to go with an LS family motor but I wanna get to 450hp in the future.

    ls6 has a different cam and heads, you're betting off finding an ls1 and getting heads and a custom cam for more power. ls6 is 10.5:1 ls1 is 10:1..... oil pans are different from the vette and fbodys too

    The bells and inputs for the M6s are different depths as well.
