Has anyone swapped a 3.8 for a 4.6? I've got a 98 3.8 5speed. Just curious how much headache it would be. I'm gonna put some money in my car over a period of time. I want to make it faster so I can at least still hear the exhaust from the Camaros and such that want to race on the hwy 🤣

From what I've read everything will work. Subframe is the same in both. That 7.5 rear you might want to change though. Having the wiring harness for under hood and computer from v8 will be necessary.
