I replaced the 350 with a Turbo 350 with a 454 and a Turbo 400 in my 71. The crossmember had to be moved to the rear 6 inches, but in the 71 the holes were already provided in the frame from the factory so I didn't have to drill.
I had to have 1/2" taken out of my driveshaft and I had to shorten the emergency brake cable. I found a yoke at the boneyard. It uses the same u-joint as the smaller yoke. Now is a good time to replace u-joints anyway. I believe the converters will swap but I would double check that with a transmission shop. You will have to provide a switch (B&M makes a kit) for the kickdown because the Turbo 400 uses an electric kickdown whereas the Turbo 350 uses a cable.
