We are in the throws of doing the early A w a 383 conversion as well.
I think we are going to make the motor mounts. I likely will draw them out and cut them out with our plasma table. We are capable of mass producing them if they fit good. Currently doing b body hp manifolds. But are experimenting w all choices. EVERY 1/8 inch counts on this swap. Have a thread going in the early a section.
