Engine swaps are justified when reliability, available parts, and torque delivery rise without overwhelming period chassis. Blueprinted originals, tasteful fuel injection, electronic ignition, and balanced rotating assemblies often achieve similar gains with less disruption. Consider future service: standard filters, accessible sensors, clear diagrams, and spare availability ensure the car remains enjoyable long after photos are posted.
Electric conversions can be elegant when weight distribution, cooling, and charging are planned thoughtfully. Preserve original mounting points, keep reversible brackets, and protect the cabin’s analog theater. Whisper-quiet torque suits coachbuilt grace, while regenerative braking eases wear. Document every change meticulously so future custodians can revert, upgrade, or maintain with confidence and historically respectful intent.
