|

Several certificated manufacturers are using the 360 Continental instead of a Lycoming (except Cessna who went the other way). I am curious if anyone has considered and/or installed a Continental 360 in an RV-7. I don't have a good feel for the overall size of the two engines
Is the 6 cylinder Continental any smoother than a 90 cubic inch/cylinder Lycoming? I read a lot of discussion about crank/propeller harmonics. All these engines are run pretty slowly compared to auto engines. It seems like power pulses ought to be measurably distinct. Consequently, I especially wonder about the effect on durablility and reliablity when modifications to raise horsepower are performed. They all have to raise BMEP, which in turn has to increase crank rap, increase the loading on the cylinder mounting flange and therefore the engine case, etc. etc..
A three main bearing crank and 6 lobe camshaft may have been great design choices in 1935, but probably not the way someone would design an engine today. I suppose that the bottom line is that the reliablitiy record is very good so I should just plug the Lycoming in, take good care of it and let it take good care of me.
