454 going into 71 C10

[FL71C10]

OK, you gas hogs have convinced me to put a 454 in my 71 SWB stepside. Now I need help. What will I need to make it fit? The motor I think I am going to get is currently in a 1990 motor home. I think I'd like to keep the stock exhaust manifolds if possible. Will that make it easier? I guess I need to get engine stands to bolt the motor mounts to. I saw somewhere on here that someone bought some tubular ones that they wer ehappy with. The trans is a turbo 400 so my automatic crossmemember should fit, right? What about power brakes and power steering pump and brakcet clearances. Will I need a special smaller booster to run power brakes?

I'm guessing I should get the driveshaft from the motor home but will have to modify it. I don't know about the radiator fan or any of those things yet.

Any thoughts or suggestions?
