    Holley came through. We now can get speed & RPM in these style gauges. https://www.holley.com/brands/holley...le_efi_gauges/ When will metric units be available?

    Except they failed miserably with the size. 4-1/2"?
    Standard big tach is 5".
    Standard small tach is 3-3/8".
    I was going to do all my gauges as the new analog Holley gauges. Guess I'm keeping my Auto Meter speedo & tach.

    I bought the AFR gauge and it was a dream to install. Only one wire from the ECU to the gauge cluster, and that one wire has the data for ALL of the gauges.

    Yes, but the 4-1/2" is the problem. Nobody uses 4-1/2". Every "large tach" is 5". The 4-1/2" is an oddball size.

    Bumping an old thread here. Does anyone know if these gauges can be re-faced? Looking to convert my Speedo to Km/H. I hear that SpeedHut OEMs these gauges for Holley, perhaps they can make a new face plate?

    I’m not sure about being refaced, but I can likewise confirm that Speedhut make these gauges. I ordered a Speedhut metric GPS speedometer & tachometer from them, and they're identical to the Holley gauges, including font and pointer design, just no Holley logo. I did ask them about ordering Speedhut gauges compatible with Holley CAN Bus, but they wouldn't do it, so I have doubts they would modify a Holley specific gauge such as the MPH speedometer, but no harm in asking! Hope it helps, Steve.
