alternative engines

Always looking out side the box and this has crossed my mind several times. Being the early A's have such a small engine compartment I was wondering if a say an srt4 from a neon would be an option. Not sure what transmission would work behind the motor. And was also wondering about hp to weight ratio. I have a 360 magnum for my build and will more than likely use it. Has anyone done such a swap or any other alternative engine in the little A bodies.
