Does it have fuel, spark (BAD COIL?) and compression?
What engine do you have ?
A good 454 will have at least 150 PSI per cylinder.
Yes, but Chevy did not make a 400 in 1985. If the car already has a v8, it is already a Chevy engine. If it is a v6, it is still a Chevy engine, but you would need v8 wiring, brackets, exhaust,etc to make it work.
Most likely a 5.7 (350cu/in)
.45
