    I'm about to go LS-Vtec or CR-Vtec and I wanted to know if anyone knew how strong either crank is. I don't know if either crank is stong enough to handle 8k+ RPM shifts. anyone know?

    You'd throw a rod before you break your crank...

    Honda cranks are VERY strong. We have a turbo hatch running over 400whp and it has a honda factory LS crank...no problems. My Civic Si has a LS/VTEC with a honda factory LS crank and I shift it at about 9k all the time with no problems. And it's not just LS cranks. We've never seen any Honda factory crank fail. I'm sure they do occasionally, but it should be the least of your worries.

    I believe it was posted that the honda crank can handle 700whp,

    with an LS/CRV bottom going high into rpms, I would suggest a crank girdle and some type of rod bolts and rods..
