Experimental engine...
Stan,
Unless you're an A&P, the engine overhaul will have to be signed off by either an A&P or IA. If you cannot get it signed off (as in our case), you're gonna have to remove the engine data plate and give it a new name and serial number. e.g. Stan-the-man 0-360, serial # 111122 (we used our Van's airplane kit #) and your engine will become an experimental engine.
I engraved a new data plate and attached it with the four pins that were carefully pried out.
This whole mess was the reason the DAR wouldn't sign our inspection off the first go-around. Neither of us is an A&P and nobody would sign our engine overhaul off...can't blame them. Everything was yellow-tagged, crank, cam, lifters, new bearings, rings, oil pump (and AD complied with), new mags, carb and fuel pump!!
Regards,
