    Not quite enough information, block casting number, 4-bolt main? Head casting number, square or oval port? Crank number, cast or steel? Dimple rods or aftermarket? The "LS6" badge was a specific engine build-up
    Sorry but people will ask, just tying to help you out.
    Looks good though.
    Anyone can pedal a bicycle, can you pedal a flat?????
