Speedometer Swap?
 

Does or has anyone done a speedometer swap to something electronic and programmable for big tires and lift i have a 1975 k10 with 8" lift 39.5x15 tires and my speedometer is way off i would like to upgrade to something that i can plug into a computer and just reprogram to work with different tires

I haven't seen any aftermarket speedos that you program with a computer. The ones I looked at had either a row of dipswitches that you set according to a table or a calibration button that you use in conjunction with driving over a measured distance.

i was thinking more like swapping in a speedometer from a newer truck like a 2010 tahoe has a programmable speedo all you have to do is plug in basically a code reader and imput your tire size and lift and it recalibrate's the speedo

Does a speedo like you are describing run directly off the signal from the VSS without any intervening processing?

If you buy an aftermarket electronic speedometer, it should come with a sending unit that screws into the stock cable hole. Then you drive a preset distance and push a button and you're good.

I'm setting one up in my nova right now.

You can go with a electronic speedo and replace your cable with a pulse generator . The all you have to do is set your revs per mile for your tire size ...Thats what I am doing with 41's .
Autometer has a nice selection of speedometers .
