    Asked by: LeeShafe
    This will bolt into your vehicle. However, you will need a Vortec style intake.

    Will this drop in my 92 gmc k1500 with the 4l80e trans.. also would the truck half ton drive train hold up to that amount of house power

    Asked by: Joshualee
    Yes, this should work for your truck. You are at the top end for torque with this engine, but it should be ok assuming everything is in good condition.

    There is no spec on what vacuum it will produce, but it will be plenty for most applications - over 10" of vacuum.

    Will my 1998 Chevy 350 vortec MPI intake manifold and factory injectors work on this engine or will I need to upgrade to a Marine intake manifold. If not how much hp can the factory injectors handle. Thanks

    Asked by: Mjs567
    A Factory Vortec intake manifold will bolt to this engine. The stock injectors are only good to 300hp or so.

    Will this be a direct drop in for a 1989 Trans Am 350 TPI (VIN 8 - L98)? I want to replace original engine. Will the factory TPI intake and exhaust manifolds bolt right up?

    Asked by: CMOS
    No, this will not be a drop in replacement for that car. It will need tuning and a aftermarket intake for vortec heads.
