Aero VS Auto Engine
Posted: Wed Apr 03, 2024 4:09 am
It’s a common discussion…comparing auto engines and aero engines… The auto engines supposedly are “hardier” in the minds of many.
But my O-300 was majored in the early ‘80s…but not put into service until ‘97. 25 years later it now has almost 1200 hrs….. at 100mph that would be about 120K miles.
Our C-145/O-300 (hp/cu-in) engines claim 145 hp at 2700 RPM.
My 1983 Mercury Grand Marquis was a 30-year newer engineered design…basically a re-badged Lincoln Town Car…. and had a 302 cu in V8…. which claimed 130 HP….. It first failed at 30K miles…(failed valve-train)….then again at 70K…(failed cam gear and timing chain)….. and then it was sold fairly inexpensively after only 7 years of family-service.
My 75-year-old C-170 with a 3/4-worn-out engine is worth between two and three times what that car cost new. (When the O-300 was majored, it was done using rebuilt cylinders…Each of which have been replaced with new Superior Cyls at some point over the last thousand hours.)
