    For the transmission and rear end its more the amount of torque it can take. Since it’s the twisting power that will cause these parts to fail.

    The rear can barely get by on decent launches from stock power.
    The driveshaft & trans def start gettin iffy on 450hp.
    Every case is different due to luck & different setups.

    Another big factor is how well your car hooks. If it hooks and catches right away from slicks or DR's, it'll def "shock" all these components and cause more stress which doesn't help. If you're spinning, it'll give alil and not cause the "shock". Hope that helps.

    Here's my input with some personal experience:
    Crank- 650+rwhp
    Pistons- 500-600rwhp with the ringlands being the weakest link
    Block- 1000+rwhp never heard of a LSx block splitting due to HP
    T56- 1000+rwhp Seen plenty of BIG FI builds using the T56. However, the clutch and shift forks are obviously upgraded....
    10-bolt- total crap-shoot.

    Put some ARP rod-bolts and forged pistons in a factory LS1 and you can go deep into the 700rwhp range. My stock bottom end made 576rwhp/590rwtq for a few years...
