Motor Length: I measured from tip of water pump shaft to rear of block. Almost even 5 (five) feet. Outside-outside manifold width is 24".
The 454 length is about 32" +-.

Front Axle weight: After comparing engine weights of a big V-8 to the V-12, it will add about 600# to front axle. I checked the data plate on my '97 Chev 1ton, and it lists 4100# GAW for front. I'm hoping the weight factor is doable since the truck won't ever be hauling more than a 1000# or so in the bed if we decide not to move the motor back.
Am I overlooking anything?
