⭕ Lycoming Engine IO-540-C4B5 . Good core for overhaul. No Prop Strike. Removed in 1999 from perfectly running Piper Aztec. Engine has 1990 SMOH (done in july 1980) and 5359 TTSNEW. I think because OH was done long time ago, this engine is not affected by recent AD on crankshaft. No prop strike . Comes with throthle body, magnetos and canadian engine logbooks. Engine is clean and was running well when removed. Bought for a Harmon Rocket F1 project. Project never went trough and now building a Midget Mustang and in need of an O-340 Stroker.
