Making a little progress.
I have a 73 quadrajet that I think will work fine. I have to convert the choke from a manifold choke to a electric choke, but I think thats doable.
I figured out how to clock the turbo to keep the oil inlet on top and the drain on the bottom, and the pipes where they need to be.
Still awaiting the aluminum to make the adapter.
what am I forgetting?
