Crank center line in '66 Cuda help needed

I used the Schumacher mounts for my 360 swap and they worked perfect. A 727 is a very tight fit in the trans tunnel on an early a body. I'm not saying it wont fit, but you will have to modify the tunnel to get it in there. For a 360, the 273 manifolds are a little restrictive. The Spitfire headers are not too expensive and they work pretty well. I have Dougs headers on my Dart and they are expensive but they work excellent.
