5.9 magnum with M122 blower/intercooler
@frosty_the_punk This is one bad *** build! You gave me a lot of ideas! What year/generation Gran Prix is the snout from? And do you know if it is interchangeable with other years? Also, what did you do to be able to fit the 4-bolt Edelbrock pulleys? I normally see 6-bolt pulleys on Eatons.
Cheers man, I need to update this with some progress. There's been a lot of trial and error with getting the accessory drive to fit in an early valiant.
The M90 grand prix snout is one I purchased off ebay, so I don't have the exact details. I think they said it's from an early-mid 2000's car but not certain.
The M90 snouts are not all interchangeable, mine is an 8-bolt. some have a different 9-bolt pattern like this one.

There are also different length options.
I remember researching that the snout with the provision for the long vertical bolt adjacent the driveshaft was most suitable for my application, but I don't remember whether the others were longer or shorter and it doesnt appear to be in my notepad.
The info is out there in forums though.
The answer to your question about the 4 bolt hub for the edelbrock pulleys is in the original post =P
I made the hub from the factory pulley on a lathe and then drilled/tapped holes to suit the edelbrock pulley pattern.
Lathe work is always an interesting experience for me since I have almost zero machining knowledge and mostly just rely on my intuition and tell myself i'll learn how to do things properly one day.
