    Hello LL, yes this engine will sit in the frame mounts if you're doing a swap. Keep in mind the parts are not application specific and you may need to change some things.

    The HP99C will not work in your truck, but we do offer two engines that will. The part number is HP31 a 350 290hp 370tq and part number HP05 383 320HP 395TQ. This engines will work with your EFI but require a custom chip, and headers.
