I have a 5.3/T56 swapped into my 1998 F150 and would like to purchase an aftermarket speedometer gauge that will work with the T56 without adapters. Is there such an animal?

Try these guys I used one of their direct fit dashes on a 66 c10. Works flawlessly

I went with Livorsi gauges. They are CAN bus gauges with a GPS speedo. The speedo updates 10x a second so it should always be on track. You can pretty much do an all in one gauge as my speedo (and tach) has a display window that shows all engine sensors.

I used an electric Autometer speedometer. Very easy to calibrate and I've had no issues.

Any reason you dont want to use the factory gauges? You should be able use a Dakota digital pulse changer. Your cluster should be 8000ppm, the GM is 4000ppm.
