67 Barracuda- Brakes and suspension on a 5000 budget- advice needed

My low budget performance build: Factory manual steering. Factory manual K-H 4-piston disc brakes with cross-drilled slotted rotors and ceramic pads. A-body 8.75 SG with factory 10 x 1-3/4 drums. Welded and reinforced 68-up K frame. Front and rear sway bars (1-1/8 and 3/4, respectively). Upgraded torsion bars (I went mild; you can go as wild as you want, but my take is more sway bar, less t-bar makes for a better street ride). Factory HD rear springs. Moog offset bushings. KYT shocks. 215-70-14 on 14 x 6 rally wheels. Doesn't sound like much but it was dead stable at speed on Willow Springs road course. As budget allows, I would upgrade wheels and tires, then shocks, then possibly a 20:1 manual box. Don't see any compelling reason to go any further than that, other than bragging rights — it already has better handling and braking than power (273 Commando/904). BTW this is not the car in my avatar picture... the blue 'vert is a slant six stocker.
