It is always a good idea to upgrade suspension to handle the added power and weight.
Where did you get the 900 lbs figure? A 454 and a turbo 400 does not weigh 900 lbs.
The added weight over a small block would be in the neighborhood of 200-250 lbs. You will need to flip the heater core too for heater hose clearance. See photo here:http://www.pe.net/~jroberts/Nova_engine_2.jpg
