Dash Tachometer

Motivation

I decided to replace my broken clock with a new in-dash tachometer – and yes, I realize having a tach on a 2-speed automatic might seem unnecessary, but I convinced myself it would be useful for monitoring RPMs during troubleshooting, especially when dealing with acceleration issues at cruise speeds (at least that’s my story!). I picked up a reproduction tach from OPGI during a sale, and the quality was excellent – fit, finish, and accuracy all exceeded expectations. Installation was refreshingly straightforward: just a single signal wire to the distributor plus power and ground connections, and I was able to reuse the existing lighting harness from the old clock to keep the wiring clean. The swap took less than an hour, and now I have both functional engine monitoring and a sportier dashboard appearance – sometimes the simplest modifications deliver the most satisfaction, and having actual RPM readings has already proven useful for fine-tuning carburetor adjustments.
