Grounding questions.

I understand that we need to ground the battery to the engine block. On an RB block, where do you do that? I have a nice spot on the trick flow aluminum intakes but with gaskets etc., is that a good spot?

The second dilemma is, if the motor is installed on rubber pads, the it is electrically isolated from the frame. Shouldn't we also ground the block to the frame? If so , where. I keep reading that you can never have enough good grounding.

Thanks for any help.
