1991 Pontiac Sunbird • 153 miles

My engine isn't what I really want and has problems and I wanted to swap the 3.1 for the 4.3 and I need to know if its possible

Nope. Too much different mountings, harness, and all components.
Why dont you just rebuild the 3.1?

To add to this, the 3.1 is a transverse mounted engine and there is no FWD transmission made to fit it and the biggest issue is that you have an operating system for one engine and one engine only, not to mention it would be against Federal law to drive it on US highways.
