V8 Tachometer conversions for Vega, Camaro, Firebird, Fiero, other GM vehicle

Doing a 4 cylinder or 6 cylinder engine swap to a V8?

One of the challenges when doing an engine swap from a 4 or 6 cylinder engine to an 8 cylinder engine is finding a way to have the 4 or 6 cylinder engine tachometer read the correct RPM for the newly installed V8. 

Fortunately, we have a solution. Our replacement tachometer circuit boards are fully adjustable and come pre-calibrated. 

Using your current 4 or 6 cylinder engine Tachometer, you can install our circuit board and have the RPM readout be correct for the now installed V8.
