I made this yesterday thinking I was going to use it for my Aeromotive regulator but I am putting the regulator on the fuel rail instead. I was fustrated and I finally figured it out. It is not polished or drilled for any holes so you could mount whatever you want. You can see in the picture that I have one for my coil that goes on the back of the head. Note, this fits Brodix BBC heads for the three accessory mouting holes in which they are 3/8-16 threads. I would imagine it will fit factory cast iron head but I am not 100% sure about that. The aluminum bushing standoffs are .800 long and are tigged on the back-side which allow me to counter bore for socket-head cap screws. I have a little over an hour into cutting machining and welding this thing. I would like to get 50.00 plus shipping.
Thanks.
