Crank center line in '66 Cuda help needed

I have started fabbing the motor and transmission mounts for the 360/727 combo going in my '66 and it seems the motor was originally offset to the right a little. I don't have any manifolds yet and don't want to have a "do over" when I finally locate some. There is alot of conflicting info about manifolds as to what will work and what won't, whats everybody else using? And if someone could give the the C/L of the crank between the frame rails I'd appricate it.



Needed: V8 drag link and exhaust manifolds!
