Here's the interior of the first Dana 427 Camaro, delivered as an SS 350 and converted to 427 power. Aftermarket column tach, aftermarket gauges at lower right, stock Muncie shifter and stock woodgrain wheel.
Baldwin-Motion 427 '67 Camaro. No aftermarket tach or gauges, not even the factory tach/gauges. Just an aftermarket wood wheel by Grant. Stock Muncie shifter.
Both photos from period (1967) publications. Both cars have drum brakes, as indicated by their brake pedals.
