Im putting a 5.3 vortec from a 2001 silverado, backed by a 4L60e transmission in a custom built rock buggy. I am building a custom dash with Summit gauges. I plan on have a Speedo, Tach, Oil Press, Water Temp guages. I am wondering how these guages sense on this truck/engine set-up. For example is Speed a physical sense(spinning cable ****) or is it a digital sensor? I'm pretty sure oil press and water temp are both physical sensors, correct me if im wrong and they do tie into the computer. And tachometer i am not sure if it is some sort of physical sensor or digital.. If someone could clarify that would be great i want to buy guages soon, and do not want to buy the wrong ones.

For instance this is an Analog Mechanical

stock gauges are all electrical.
Ect uses a thermistor, oil pressure uses a electrical transducer,vss a magnetic pick up, tach signal probably from the ignition system.

It would be easy to use the factory cluster...you don't like it?

Thanks a lot Tech2! I just figured it would be more fun and look a lot nicer to build my own from aluminum, I'm running a fuel cell so I won't have a gas gauge but I and just focused on the essentials. I already spent 240 bucks on these 4 gauges and they are all electrical gauges except the speedo is mechanical it utilizes the cable.... Idk if there is a way to convert it to a mechanical pick up? Seeing as I have 4.56 geared axles and will be running 40 inch tires.. It might be easier to calibrate the speedo as supposed to buying one of those electrical calibrators. I just figured gauges set in aluminum would look real plush

This is what the cardboard mock up of the dash I built looks like
