Anyone out there with any experience dropping a 383 into an '84?  Specifically, I am wondering how much modification or fabrication I'm going to have to do with the accessory brackets.  The motor I am building has Dart aluminum heads, Edelbrock manifold and Edelbrock Performer series 700 cfm carburetor.  Another challenge that I'm sure to face very soon is with the wiring harness.  Any advice from experienced members would sure be appreciated...
