Possible heat soak of the starter or the timing is set too high.
Hey Fred==You probably have carb problems. Have a good mechanic overhaul it for you. GoodluckJoe
Anything can be done with the right amount of time and money... but the main question here would be WHY?
I would venture to say that it's required as it's a high performance engine.
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.
It would do just as fine on a Trans Am as on any other car.
Go to manheim gold.com and see.
Try putting the pedal to the floor while cranking it
As far as going in the engine compartment and bolting to the transmission, and Pontiac, Oldsmobile, Buick engine will work. You may have a duel pattern transmission which would allow you to use Chevy also. You would have to look to know. Where the trans. bolts to the engine there will be two holes side by side. Al GM except Chevy are the same as far as bolt pattern. Any motor will work, it's just a matter of running the plumbing, electrical and exhaust.
Trans Am parts would simply be parts from a Pontiac Trans Am, potentially used in restoration, or maintenance to keep the car running or looking good.
If it's an automatic your looking at $2,500 installed.
Check the 2001 Grand Ams crank shaft position sensor first. If the sensor is bad then the engine will not get fire or start.
There is a 1976 Pontiac Trans am on eBay for a good price that you could look into. I would suggest looking into craigslist and seeing what is available in your area.
