I have a 347 so I needed a good balancer (to anyone putting a supercharger on, I highly recommend putting a high quality balancer on your motor! the factory one will come apart)
To make the belt system line up correctly, FRPP makes billet crank pulley spacers. You will need one to make this work.
When I ordered the blower bracket I opted for the studs to install it and I highly recommend it! way easier as you can see in the pics below. I had to make some adjustments to my acc bracket and the blower bracket due the the type of cyl heads I'm running, but for anyone running factory or factory type cyl heads you can have the blower bracket installed in 20 mins or less! (or less then two beers!!)
