Using unconventional/uncertified instances of instruments is what experimental is all about. That's not the same as not having any airspeed, altitude information presented.

I learned at Sun-N-Fun that our friends to the north (TCCA - Canada) have an "owner maintenance" category for previously certificated airplanes that are more than 30 years old with no manufacturer support. The example was the presenter's Stinson 108. He has replaced all of the instruments with Arduino-based, digital units. Awesome!!!
PS. Yes, the airplane airworthiness in the certified category is no longer valid.
