alright well i got the ls1 one in today. found out that the ls1 does not have 2 drilled holes towards the back of the engine for 2 ground wires like my 4.8 does. now my question is can i just hook up these two grounds somewhere else on the block? what about the heads? can i put them on the heads by any chance and not have to worry? one other option i may have is can i connect 2 ground wires to the same spot/hole?

 

yes too all ahhaha
