Well, I've got to say it brought some tears to my eyes to see that motor come out of that car.
I'm just one of those old-farts that would have a difficult time (except for those suspension/brakes changes), making the major changes you have going here.
I will never forget getting the call from McManus Chevrolet (67th (South) Western, Chicago) saying they were just unloading it off the truck back in April 1966. I couldn't get there fast enough... I envy you and the fun you must be having with this transformation. Best of luck!!
