I noticed the ground for the starter bolts to the transmisson bell housing, so would that ground out the transmission anyways? Or would it be best to add a dedicated ground? As far as the engine block, does it matter where on the block you bolt the wire to? And it's a better ground connection if you bring the wires to the battery correct? or is it better to actually go to the frame? My battery has a dedicated wire to the frame so I'm not sure.
