I have printed out a Lycoming PDF which shows and explains all of the letter-designators after the intial 0-320 prefix. I also understand that certain model numbers were created when installed in certain production A/C, etc.
But as a real rookie in this engine stuff, how the heck is a guy to choose "the most ideal" model number? In a previous post, I asked for O/H advice, based on getting a used 0-320. However, the gentleman selling me the engine has dozens and dozens of 0-320's. Each one is sitting there on huge pallet racks, as far as the eye can see. Additionally, each one has a large cardboard description attached to it- showing TTSN, TTSMOH, log books, model number, etc. Gazing up at all these engines, I honestly get so confused looking at all the different model numbers that it seems to be a ****-shoot which model to choose? Keep in mind that despite whatever time may be listed, I still plan to O/H the engine before flight.
The nice thing is that I am a LONG way from actually "needing" and engine, but I'd like to go ahead and get one so I can work on it throughout the project, and as funds allow. Somewhere along the way, I also got this idea in my mind (from reading many posts on Lyc's) to stay away from the H2 models. I know they had some issues way back when. However, the gentleman with all the engines tells me he wouldn't let that bother him. He says the H2 models are REALLY easy to do inspection checks on, since many parts are easy to inspect based on configuration. He also has tons of them, and says they are "very tough".
So now I stand there and look at dozens of perfectly good candidate engines, but don't have the knowledge to point to one specific model and say "that's the one I really want". Can anyone help? Again, I know there are many-many versions of these Lyc's, and surely I can't be the only one who is perplexed by all the model numbers.
If it were you standing there, which one would you try to seek out, and which one would you not consider? By the way, the seller isn't biased one way or another, and isn't trying to steer me in any specific direction. He'll sell me whatever I want, and this is where it gets really confusing for me.
Thanks for any/all input. I hope I am not the only one out there with this dilemma (of not knowing the best choice when choosing from dozens of models).??? Imagine my confusion when staring at rack after rack of Lycomings.
Take care,
