What is the general consensus on using the lycoming and continental ground power unit engines as cores to build airworthy engines. Specifically I am looking at a continental O-470 that was used in a GPU or APU role for the duration of its life. I have the choice of several but I view them all as nothing more than good starting point cores. As well, I do recognize that I will be starting from scratch for accesories as it only comes with one mag, and a non-aircraft carburator. Also, I plan on going with a fixed pitch prop. The reason I am considering it is the price for the core, with a guarantee on the crankshaft, case and jugs is 1K. Any and all opinions greatly appreciated. Thanks.
