What happens here

Ensure the car's mechanical and powertrain components match the 1993 specifications. This includes verifying the steering box (e.g., 12:1 ratio), spring rates (e.g., 900 right front, 800 left front, 275 right rear, 225 left rear), and sway bars (e.g., 1 1/8 inch bar). The engine should also be rebuilt and dyno-tested to achieve the period-correct horsepower (e.g., 700+ hp) and run smoothly.

Goal: Ensure mechanical components match 1993 specifications.

Tools and materials

  • Engine Dyno — Testing and tuning the rebuilt engine for horsepower and reliability
  • Engine Parts — Rebuilding the engine to period-correct specifications
  • Mechanic's Tools — General assembly and maintenance
  • Steering Box — Replicating period-correct steering performance
  • Suspension Springs — Achieving correct spring rates for period suspension setup
  • Sway Bar — Replicating period-correct handling characteristics
