swapping a 440 into a a body

Just buy the Schumacher mounts. Its easy to do. Do a little trimming on the driverside motor mount on the K-frame for oil pump clearance and drop it in. I would recommend get the shims for it. On some car you need to shim the motor up a little for oil filter clearance. You will have to watch water pump clearances. You will have around 3 1/4" to 3 1/2" clearance between the pump and radiator. You will also need the right oil pan

A little trimming? Well.. with the biscuit mount, there isn't much left when you are done which is why they tell you to run the torque strap. If you go with the Schumacher mounts I'd get a spool mount K.

+1 on the shims. They also help with header fitment.
