    You can start this engine, but will need a tune to make it work properly.

    Asked by: Jina
    This is an LS series engine so you will need a complete engine swap kit to use this in your application.

    Some other LM7 5.3 crate engines that are offered, indicate 2WD or 4WD applications. Why would that differ? Does this engine work in a 4WD application?

    Asked by: mclemore1222
    This is shown to fit either 2wd or 4wd application as shown on the fitment tab.

    What gives this motor more horse power than the stock 5.3? Does it just have a cam in it or head work and other stuff?

    Asked by: Hayes19
    Hello Hayes, Yes, its a custom grind camshaft matched with upgraded springs and .030 over bore gaining a few cubic inches.

    Can this engine be used to replace a 2007 avalanche 5.3 with AFM? Would all I need to do is an AFM delete tune to delete this and make this engine work in this application? All other sensors of existing engine work in this application?

    Asked by: PJ Pirate
    The HP97 will not work in place of a AFM engine, as is uses a different blocks, harness, reluctor wheel and ect.
