Except his wheel wells ARE NOT the same as a Barracuda. Swingers, Valiants, Scamps, etc have a full INCH less space in the wheel wells than Dusters, Demons, Dart Sports, and Barracuda's. Which I've even already mentioned in this very thread. The widest tire's you can get on the Swingers is a 275, and that's after a spring offset kit and usually a quarter lip roll. You can't get 295's on a Swinger without a mini-tub. Not only that, but the wheel arches on the rear of a Barracuda are much higher, so you can cheat some and hang the tires outside of the quarters a little if your ride height has some rake. The low wheel openings on the Swingers mean you can't get away with that unless you jack it up like a 4x4 in the back. And I don't even mean like 70's street freak style, you'd literally have to raise the back end of a swinger a good 6" or more to do that. Or cut the wheel arches like the factory Hemi darts.
The 833 is a good option, like anything it just depends on your plans for the car. If it's just an around town car that doesn't get driven a lot you can get away with 3.91's or 4.10's maybe. There's no way in hell you'll be able to spend any time on the freeway with those gears though, I think the 3.55's are pretty much the limit for any kind of freeway driving much more than 30 minutes or so.
The conversion to an 833 has a pretty wide range of costs. If you go to Brewers I think you'd end up with a quote somewhere around $3,500. They don't list their price anymore for their full conversion kit, but I recall it being close to that. But, all the parts are factory, so, you can find them all used too. And that can drop your price pretty substantially if your patient and get decent prices on used parts. I think my conversion initially was between $1,500-$2k when I did it. But I gathered the parts over a couple years, found an 833 for only $500 and rebuilt it myself, etc. So it just depends on how you do it. All new parts etc will probably be around that $3,500 mark, all used parts could be half that pretty easily if you can find everything for a good price.
