anything is possible with $$$... your question is to vague! need more info... year, and engine info!
Maybe
Yes
While I don't have exact figures, I'd imagine the Firebird was the quicker. It's a lighter car. It also depends on rear end gears, tranny, etc.
Ram air, a stronger V-8, different hood, special, wider wheels, tighter suspension,
you can put a blower on nearly any motor
yes all 4th generation(1993-2002) firebird parts should fit in other 4th gen firebirds
NO! the Montana is a front wheel drive minivan and the firebird is a rear wheel drive, even if they were both rear wheel drive for some reason, the firebird engine would shred the wimpy minivan trans and it would be just wrong to put a minivan trans in a firebird.
Ram Air can't be mistaken. The dual functional hood scoops along with the custom air cleaner pan is pretty telling. If you mean how can you tell if a particular Firebird is supposed to have it and doesn't.......you'll have to send the VIN to Pontiac Historic Service. For a fee they can tell you what the car was equipped with.
yes
Yes.
Not with out major modifications.
the Italians helped put together a engine so the ram can haul better
