Your best bet is to run a separate long ground cable from the battery directly to the engine block, then take a short ground cable from the engine block to the frame. Attach it to the engine and frame with a 3/8" bolt and it is a good idea to make sure it is contacting bare metal if possible. Engines are often electrically isolated from the frame and it is critical (for the starter and ignition system) that they get a good ground. Grounding this way is a a hassle and costs a bit more, but it should save you problems down the road.
