Good evening,
I have a 1987 Monte Carlo SS with a 454 BBC swapped into it. It's running an HEI distributor. I am having a hard time getting an accurate RPM reading inside the car because the gauge is reading really far off from what it should be. For example. When the car is idling at probably 700 RPM the car is reading close to 2,000RPM. What should I look at or buy or modify to get this to start reading accurately.
Additionally. The OEM wiring harness has been hacked so many times... I am having a hard time finding the OEM wires that were used to power the Water Temp Gauge and the factory Oil Pressure gauge. Currently I only have a working Fuel Tank gauge and Volt Meter.
I'm not concerning myself with the Speedometer until I swap the T56 in and know that I have a working transmission /sending unit set up.
Any help you can suggest would be great! Thank you!
Ryan
