Sway bar kit??

I'm ASSUMING by your avatar you're talking about a '67 Dart? If you just got a 360 into it, does that mean it was originally a /6 or 273? First order of business getting it to handle is upping the ante on your torsion bars, then getting an anti-sway bar and better shocks to compliment your t-bar choice. Lots of choices out there, including but not limited to: PST, BAC, Hotchkiss, Firm Feel, etc. Most even have upgrade packages to get you to your goal. Talk to them, and I'm sure others here have their personal favorites, too.
And don't forget- all the upgrades in the world won't do you a speck of good if the rest of your front end isn't up to snuff first- i.e. ball joints, bushings, etc.
