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.
On a small block Chevy the distributor goes through a hole in the intake manifold. On a Pontiac the distributor goes behind the intake manifold.
yes. the last year of any Pontiac v8 was the 301 in 81. the standard engine in the 82 and up firebirds was the corporate engine-the Chevy 305
Pontiac uses same block no small or big, Chevy describes their engines small or big
No
The firing order for the Pontiac 400 engine is that the small block powers the big block.
no
No. The Pontiac headers will not bolt up to the Chevy small block.
No, not even close. Pontiac 350 intakes will interchange with 1965-1979 Pontiac 389,400,421,428,455 intakes. Most all aftermarket Pontiac V8 intakes are designed for the 1965 up bolt pattern. 350 Chevy is part of the small block Chevy engine family, and virtually nothing interchanges with a Pontiac V8.
YES! You can put ANY small block Chevy into a Fiero. Visit here, http://www.v8archie.com/, there you can find the conversion kit (minus the engine) and answers to all of your questions.

I'm not sure why you'd want to put a small block Chevy in that Pontiac. But some things to keep in mind....most of the engine wiring is on the opposite side. You'll need to change engine mounts on the frame and you'll also have to make sure to get a Chevy transmission as the B.O.P.C trannys won't bolt to a Chevy.
