We install Holley EFI Gauges in our 1974 C10 Square Body. Blake and Lucky Costa yank out the old cluster and custom fab a nice fitment of the new gauges keeping the stock look but utilizing current technology by Holley.

Just because you demand the most sophisticated electronic fuel injection technology available on the planet doesn't mean that you can't appreciate the subtle sophistication of a beautifully crafted analog gauge. In fact, purists know that while some information is well displayed in digits, other information is nearly worthless if you can't get a feel for the rate of change from the sweep of a needle.

If that paragraph describes you then your gauges have arrived. Holley EFI's new Analog Display Gauges use digitallydelivered information over Holley's sophisticated CAN bus but use a traditional sweep display. And while you can appreciate the beauty of nice analog gauge it is important to understand the additional benefits.

First, these all get their information from the Holley ECU, meaning that you don't have to run wires all over the vehicle to get the information you need. You get everything from the ECU itself.

Second, because it uses Bus communication technology, all you have to do is run a single CAN bus harness to the ECU and then daisychain the gauges. Did you ever think that installing gauges could be so easy?

And just take a look at that mounting system. Remember the old style gauges where you had to fumble with a pair of tiny nuts up behind the dash to install the gauge? Those days are gone and good riddance! These gauges feature a threaded body that allows a single bezel nut to hold the gauge firmly in place. Too easy.
