99-01 32v 320bhp motor. Is it the same as the Mach 1 motor?

Hi.

My Mach 1 and I are in the UK, so most of the options open to you guys are not practical for me. My motor has a big-end bearing failure (oil starvation, my fault) and I'm about to pull the motor to rebuild the engine. This will take some time as I need to strip before I can order parts, which then need to ship from the US.

A 2000 320bhp 4.6 32v Cobra motor has come up on eBay and I'm wondering whether I should buy and fit that instead. It's eBay item 173248183077 for reference. The code on it is 0G839AA. I'm confused as I thought the Cobra was supercharged, but this motor doesn't have a supercharger. I also thought it ran a lower compression ratio, so would be a dog without the supercharger.

Can someone who knows their modular motors tell me what the differences are?

I will message the seller to ask similar questions when I get home and have access to my eBay password.
