The 22 is a Schiada. Harder to find because they weren't made as long, buuuut the upside is that they don't appeal to as many people so they are sometimes more afordable than the 21s. Corleone actually has one in his driveway, so when you go out to look at the Continental, maybe you could have a peek at that as well. I thought that I saw that it was for sale as well, but that didn't make much sense, so I'd call him on that. If you do a quick search for posts by him, you should be able to find pictures of his 22 project.
Hustler's boat is a Hustler. Its 22' ?" slacker deadrise at the transom than a Spectra as far as I remember. The entry on the hull might be a little slacker as well. His boat is nice and gets used A LOT. I the years that I've known of his boat, I've never seen another one like it, so finding one would be tough. As far as performance, last I heard 800-900hp was getting him right around 75, but I know he's changed some hardware that might have improved that speed dramatically. PM him and you might be able to get more info.
One more thing.... The PMs on the boards don't always work, so if you need to get a hold of someone that you have a phn number for, its quicker and easier to call em.
