    Arrow LQ9 information..

    can someone give me a link or explain the LQ9 6.0l

    looking at it, it has more displacement and torque than an ls1 but roughly the same hp, why is that?

    is it basically a direct swap with a '98 ls1, or is there much more involved?

    would you suggest an ls6 or an lq9 to replace?

    thanks guys

    Because engines don't make horsepower, they convert fuel into torque. That is a function of displacement. Horsepower is a function of that displacement and RPM. The truck engine does not generate as much torque high in the RPM range as the LS1, by design.

    I left things out for the purpose of oversimplification.

    It has more displacement, but also has heads and cam designed for lower end torque.

    My stroker is a LQ9.
