A am near applying for an airworthiness on my project and

I see AMA/EXPR as engine manufacturer and UNKNOWN ENG for model

Is it advisable to use that declaration? I use an electronic
ignition and non factory fuel system. So it is not a certified
engine.

Paul,

To make it an experimental engine you will have to remove the original
data plate. Actually, you can just flip it over and stamp it with
something like "Paul's Experimental Engine, Seral Number XXXX". From
that time on, it will be an experimental engine. In the event that
you sell the engine, (or install it on a certificated airplane)
conformity with the original type certificate will have to be
established by someone before it can be returned to a non-experimental
status.
