Would an LS4 V8 fit into the engine bay of a 1992 Buick Regal with the 3.8?

I have the Limited Coupe if it makes a difference. I've already decided that if my engine goes, which if I'm lucky won't be for another 60k miles, I want to replace it instead of getting the old one rebuilt, and I definitely want a V8. The only GM V8 I can find designed for FWD is the newer LS4. By chance, anyone think I could get a Buick 350 in there? Buying a different car is out of the question so don't suggest it.
