Lycoming engines, cross-reference

[wampach]

For those of you looking for an acceptable engine model for an airplane
project, may I suggest a call to Lycoming in PA at 717-327-7274
publications department? For about $5.00 they will send you information
on their publication SSP-393 Certified Engine List. It covers every
model from O-235 to IO-720.
It is easy to use. Find the engine you are interested in on the list, it
gives you: horse power, TO RPM, Fuel type, and Compression ratio and
most importantly same as or similar to another listed engine and the
differences. Such as magneto type, carburetor, Fuel injector, fuel pump,
fixed or constant speed propeller, counterweights, prop bolt mounting
size, engine mounting configuration, and a lot of other good stuff.
This is approved data acceptable to the FAA. I have used it to modify
engines (with a 337) to meet the requirements to be used in a different
airplane with different propeller and carburetion. This should make
picking out an engine for your project a simple task.

Another publication you all should have in your Lycoming library is
service letter number L114; it gives a complete listing of special
service publications.
