Re: Ground strap
I too have aluminum heads and a battery in the trunk. I am not an electrical engineer, but I don't think that making an electrical connection in your system with aluminum heads in the mix is going to cause problems. In my case, I ran two straps:
- In the front of the motor from the block to the subframe. I used the fuel pump location (I have a blockoff plate) directly to a hole that was already in the subframe nearby.
- In the rear of the motor, from the back of the head to the body of the car, near where my positive battery cable from the trunk came down to the starter.
I can give you more details and pictures if you need them.
