Quick update - I got the top engine plate swapped for the Edelbrock one.
I installed the Edelbrock cast tensioner bracket, the new tensioner, and the cast idler bracket that bolts to the water pump.
I also pulled the Power Steering Reservoir - and removed the GM bracket - and swapped that for the Edelbrock bracket. It moves the reservoir more towards the drivers side of the engine bay.
Also - my 3.25" pulley came in - so I should be running about 8-9.5 PSI when I get the car tuned.
I still need to pull the bumper - install the intercooler, the brackets for the IC pump, and the blower itself.
I will probably pull the bumper tomorrow and get started on all of that.
Now for some pics:
