3.7l to 4.3 engine swap

[89sebring]

Hello all,
I currently have a 1990 regal Sebring with a 3.7l that’s getting tired. I know regal produced this current model with a 3.7 and a 4.3 option. With that being said the boat has mounting options for a v6 from the factory.
If I have a complete 4.3 engine how hard would it be to find the correct Ypipe and to install?

Depends on what you have as a donor. Just the block will be an exercise in frustration. A complete donor boat is the best option. Many needed parts they you wouldn't think of

Need to change the mounts too.
