    Was wondering what mods I can do to get around 280-300 hp 375-400 tq?

    I'm new to the 5.7 vortec motors, I do plan on installing a cai and exhaust

    Any help would be greatly appreciated

    All depends on your budget...

    Performance intake manifold, ported cylinder heads, cam, headers, CAI, hi-flow cats.

    Depending on the miles on the motor, the block should be clearanced. If that is the case, get the Crank balanced, and go with flat top pistons.

    A good rebuild by a reliable Engine shop, with the items mentioned above will run around $3500.
