Recommended Modifications
Headers, dual exhaust, large cfm carburetor, performance ignition and increased compression of 10.25:1 and above is required. Cylinder head modifications would be beneficial. Use with automatic transmission with high stall torque converter or manual transmission. Close attention to proper ring and pinion gear set and tire diameter is imperative.
